The Wolfcastle Family are the relatives of Rainier Wolfcastle, a self-described "steroid-abusing, pot-smoking, woman-groping, son-of-a-Nazi, washed-up, has-been movie star" ("See Homer Run") who seems to live in both Hollywood, California and a mansion in Springfield Heights. Rainier Wolfcastle is originally from Austria, but in other episodes he is mentioned as being from Germany.
Summary[]
First appearance of Maria Quimby at the Quimby Compound in "The Boy Who Knew Too Much".
Rainier Wolfcastle has at least two school-aged children: daughter Greta and son Dieter. Their mother is Rainier's ex-wife/wife/ex-wife again Maria Quimby of the influential Quimby family with a sometimes fuzzy continuity on their marital status. The snooty bullies at Greta's private prep school taunt her with, "New money always cry." ("The Bart Wants What it Wants") His interview for Eye on Springfield is about his recent bankruptcy blaming 3 divorces in 3 months ("The Strong Arms of the Ma"). The announcer for "Up Late with McBain" was Obergruppenführer Wolfcastle. ("Cape Feare")
Henry Louis Gates gets his TV crew on "Finding for Roots" to bump the next guest for Carl. In the nearby dressing room Rainier is looking at the Wolfcastle family history "Book of Life" and just says, "Ah, it's probably for the best." ("Carl Carlson Rides Again")
Simpsons Comics[]
In "Bart Simpson Comics #53: La Bart Vita" a newsman covering the premiere for another McBain movie wants a reaction from Rainier Wolfcastle to allegations he was born in Bern and rather then deny or confirm it, he punched out the reporter while shooting, "You dare call me Swiss?!"
In "Simpsons Comics #181: Better Off Ned" Marge convinces Ned Flanders to go on a week-long Christian singles cruise while Rod and Todd stay at the Simpsons. Ned is enjoying the cruise until he and another passenger, Tracy Carlyle, are thrown overboard and stranded on a deserted tropical island which might have aliens hiding on it. Tracy repeatedly throws herself at Ned and gets him to rescue her from the jungle except the aliens are just part of a movie shoot starring Rainier Wolfcastle and this was planned by Tracy to make Rainier Wolfcastle jealous since he is Tracy's husband (Ned never reads tabloids so he had no clue). Tracy's plan backfired because she and Ned were presumed dead and Rainier had gotten married again. Tracy then meets his "latest sequel" Citronella Marpoza AKA Mrs. Rainier Wolfcastle VI and the two women cat fight as Rainier's manager tells him, "This is bad, Rainier! Bigamy doesn't test well!"
In "Simpsons Comics #194: Homer Simpson: Canine Decoder" Rainier Wolfcastle has heard from Mr. Burns about Homer helping his guard dogs and needs him to do the same for overly nervous puppy Mendoza (named for Senator Mendoza, his fictional character McBain's archnemesis). Homer figures out the nervousness is being caused by identical twin boys playing too rough with Mendoza and while Homer assumed they were Rainier Wolfcastle's son, he insists they are not his and just the sons of his executive assistant even though they look exactly like him.
In "Simpsons One-Shot Wonders: The Wonderful World of Lisa Simpson (Honey Pooch Pooch)" Lisa enters Santa's Little Helper into the Springfield Precious Pooch Pageant and there is another greyhound named Maximus owned by Rainier Wolfcastle.
