Tentative title: The Great Day.
The recap featuring the scene with Chao-Li and Angela from the preceding episode's finale contains additional footage. Although the conversation between them in # 169 alternated between close-ups of both of them, the final moment when Angela tells Chao-Li that Chase's second codicil will leave her with everything Chase owned was presented completely with the camera on Angela in the previous episode. The recap, however, features a close-up of Chao-Li in which he smirks at the end — a part that was not used before.
All outdoor scenes for this episode are filmed at Saddlerock Ranch and in the surrounding Malibu Canyon, especially the opening scene with Richard and the scene with Tony and Shannon near one of the stables at Falcon Crest as well as the scene with Lance and Tony at the lake.
The Gioberti Family Cemetery set is now built on the Saddlerock grounds for this episode and # 171 as well as 177 and 183. Compare especially # 183 (screen grabs and explanation) for details.

Melissa presents various renderings for the wine labels of Joseph Wineries. She describes the first one as a view of the valley. The painting on that label is the same as the one used on the label of a Gioberti wine bottle in the series predecessor, "The Vintage Years" and on a Zinfandel bottle in # 102 (compare there). The picture will also resurface again on a Cellini wine bottle in # 192 (compare there).
Detailed information about the Gioberti wine label from "The Vintage Years", the artwork draft for Joseph Wineries from the current episode and the Cellini label from # 192 as well as about many other labels is available in the Show – Production Office – Wine Label Gallery section. Previews are available for the general public; for DFCF members, the wine labels are available in high resolution.

It is one of DAVID SELBY and CARL HELD's wonderful improvisations when Garth blocks Richard's way in his New Globe office.


License plate number of the Rigg real estate agency's burgundy 1985 Ford LTD Crown Victoria Country Squire Station Wagon with exterior wood trim: 2IRI476.
By the way, this is the same picture car that was used as one of George Buckman's vehicles (compare # 166).

Fictional entity: The name of the real estate agency Alison works for is Rigg.
Inside joke: The company name is "borrowed" from writers' assistant NANCY RIGG.
The home Maggie and Richard purchase this episode (and where also their wedding is supposed to take place) is the main house of Saddlerock Ranch in Malibu Canyon in real life. This will be the major filming location for the rest of this year and the following season.
On 11/09/2018, the Woolsey Fire, a destructive wildfire in Los Angeles and Ventura Counties, destroyed many parts of the Saddlerock Ranch, including the main house.
Carly is listening to "Heat Wave" (1967) by MARTHA REEVES AND THE VANDELLAS in front of the Fixx House.

Product pleacement: Lance's instant camera is a Polaroid Spectra (distributed as Polaroid Image in Europe), which was put on the market in 1986.

DAVID SELBY's picture on his main title card comes from a scene in this episode.
Post-production mistake: In the editing process, the shot of Richard was accidentally flip-flopped on his main title card.
During Richard's bachelor party, an all-girl band plays a jazzy version of "When the Saints Go Marchin' in", an American gospel hymn.

Product placement: The drum used by the girl band at The Max was built by the Pearl Musical Instrument Company.


Lance's song, "Knock on Wood" (original version by EDDIE FLOYD, 1966), during Richard's bachelor party is performed by LORENZO LAMAS himself. Inside joke: LORENZO released his own album around that time — perfect promotion!


Product placement: Perrier-Jouët (Fleur de Champagne) is poured at Richard's bachelor party.


Uncredited extra DOUGLAS MAIDA appears as Dave in this episode again — this time, as a patron at Jeeter's.
Compare # 224 for biographical details about this minor rôle and a list of appearances throughout the series.
For details about the extra, compare # 034.

Maggie and Richard have soft drinks at Jeeter's, previously known as Nick's Diner, but now renamed and refurnished as a 1950's style diner with a jukebox and cozy booths with leather sofas. It is actually a part of the CBS-MTM Commissary (compare # 163 for more information) and will be used for # 171, 174 and 177 this season, too.

Product placement: The jukebox at Jeeter's is a Wurlitzer Stereophonic (model 2310 S); it was available from 1958 on.

The song playing from the jukebox at Jeeter's is "I Second That Emotion" by SMOKEY ROBINSON AND THE MIRACLES (1967).
Despite LORIMAR's "new wardrobe for new season" policy, this episode, Lance wears the same shirt he already wore in # 127.
The interior set of the reception hall in San Francisco where Melissa presents her new product line of wines is the redressed set of The Max nightclub. The balustrade of the mezzanine level was simply dressed with a decorative cloth.
Deleted scenes:
  • The director's cut contained a restaurant scene towards the end of act 3 in which Richard and Maggie have a night-before dinner with Vickie. Everybody wonders where Eric is. While this scene was removed in post-production, the following scene (Eric sneaks into the Falcon Crest Victorian Mansion) remained intact.
  • The original act 4 opener was a scene with Eric and Vickie at their house in the morning of Maggie and Richard's wedding. They get dressed for the reception. Eric says he has an errand to run for Richard. This scene was also cut in post-production.
Post-production mistake: The establishing shot of the Falcon Crest Victorian Mansion at night is one of the clips shot during the shooting of the fire scene for # 103 (compare there), which includes the false gable that was specifically built and burnt down. The same mistake occurred in # 115, 125 and 137 already.
When Eric is seen hiding behind the wicker armchairs on the terrace before sneaking into the Falcon Crest Victorian Mansion, some odd black spots are visible on the stonework of the Mansion's main tower. It seems that these are spalls in the coating of the set, which is only made to look like stone. It remains a mystery why and when the set was damaged, but the set construction crew apparently failed to repair the damage.

One of the garages at Saddlerock Ranch and the driveway leading to it pose as vintner Purdy's garage and driveway.

The scene with Emma and Curtis in front of the ranch guest house is filmed at the real Saddlerock guest house.
After his earlier appearance in this episode (see above), uncredited extra PAUL VAN also plays his usual rôle of the mustached Tuscany Valley doctor as a guest at Maggie and Richard's wedding. During the ceremony, he is sitting next to the gray-haired socialite, his colleague from the hospital (SHARRI ZAHK, see below).
Compare # 227 for biographical details about PAUL VAN's primary minor rôle and a list of all his appearances throughout the series.
For details about the extra, compare # 014.
License plate number of Angela's anthracite gray 1985 Cadillac Fleetwood 75 limo: 2EAK705.

The gate guard at Richard and Maggie's ranch, who checks the invitations, is portrayed by JOE STONE. He is a key stuntman in seasons 6 and 7, who played various rôles already. Compare # 183 for a complete list of appearances.

Uncredited extra SHARRI ZAK appears as the gray-haired Tuscany Valley socialite with the pony tail again; this episode as a guest at Maggie and Richard's "non-wedding" where Angela speaks to her.
Compare # 202 for biographical details about this rôle and a list of appearances throughout the series.
For details about the extra, compare # 009.
The interior set of the ranch's guest house (bridal room where Maggie gets dressed) is the same set as the sitting room and bedroom set in Richard's third Tuscany Valley home — it just underwent some minor redecoration and was refurnished.

Uncredited extra KEVIN G. TRACEY appears as the thick-eyebrowed Tuscany Valley gentleman again — this time as a guest at Richard and Maggie's wedding.
Compare # 185 for a list of all his appearances throughout the series.
For details about the extra, compare # 001.

When Maggie walks down the aisle, RICHARD WAGNER's (1813 – 1883) "Bridal Chorus" from "Lohengrin" is played.
The pool where Melissa and Carly have their argument is the real Saddlerock swimming pool.
Season time frame:
With the information given in # 171 (Angela's check dated 02/15/1988 — see there), certain dates of events in the current episode can be derived from the dialog:
Emma refers to Richard's bachelor party "on Thursday". Angela speaks of Maggie and Richard's wedding "on Saturday". They obviously refer to Thursday, 02/11/1988 and Saturday, 02/13/1988.
Since # 165 depicted the events in July 1987 and the harvest at Falcon Crest took place in # 168 (Carly picking grapes — obviously an early harvest, probably around August 1987), approximately half a year must have gone by between # 169 and 170.
