Three years after What's Up Doc? was released, Porky Pig would star in a short called The Wearing of the Grin (1951), which was one of the titles on the fake marquee.
The lyrics for the song "What's Up, Doc?" are heard for the first time during What's Up Doc?. The song's tune had been first used a few years earlier, usually over the title credits of other Bugs Bunny cartoons. This cartoon appears in Looney Tunes Golden Collection, Volume 1, CD 1. It is followed by several other Bugs cartoons using the instrumental version of the theme in the intro.
During What's Up Doc?, Al Jolson, Jack Benny, Eddie Cantor and Bing Crosby appear, through caricatures, in a park with Bugs, all of them out of work. Jolson spots Elmer, a big vaudeville star, and tells the others that Elmer is looking for a partner. The four then do their trademark phrases/songs, but Elmer ignores them. When the "fathead" reaches Bugs, he says, "Why are you hanging around these guys? They'll never amount to anything."
Frigid Hare marks the third time that Bugs Bunny apparently took a wrong turn at Albuquerque. The first was in Herr Meets Hare (1945) and the second in My Bunny Lies Over The Sea (1948).
Elmer: Hey, pinhead! You know how to make antifreeze?
Bugs: Yeah. Hide her nightgown!
The CBS version of What's Up Doc? left in the "antifreeze" joke, but cut the part after that where Bugs slams a pie in Elmer's face, sprays him with seltzer, and whomps him with a mallet before jumping out of his clown suit and shuffling offstage and the part where Elmer holds a rifle to Bugs's mouth.
In the sequence from What's Up Doc? where Bugs is in the traveling vaudeville show with Elmer and decides to come up with a new act so he won't be made a fool like he was in the previous scenes, the version that aired on ABC cut a slightly risqué joke between Elmer and Bugs (about hiding an auntie's nightgown) and the part where Elmer holds a rifle to Bugs' mouth after Bugs upstages him. This was also cut when it aired on The WB.
What's Up Doc? is 7 minutes long.
What's Up Doc? was released on June 17, 1950.
On the ABC airing of The Grey Hounded Hare, the part after the dog falls from the sky after chasing the balloon rabbit, where the greyhound goes to punch Bugs, but gets distracted by the electric rabbit on the track and Bugs sidetracking the dog by using a dynamite stick to play fetch with him (resulting in the dog getting blown up), was cut, making the cut seem like the dog blew up after he fell from the sky
The Grey Hounded Hare is 7 minutes long.
The Grey Hounded Hare was released on August 6, 1949.
Frigid Hare is available on the Looney Tunes Golden Collection: Volume 1, uncut and restored.
On a 1965 telecast of Frigid Hare during The Bugs Bunny Show, Blanc overdubbed Bugs' "July 1953" line as "July 1968", to put the date in the future again.
Frigid Hare was initially banned from airing on the 2001 installment of Cartoon Network's "June Bugs" marathon due to the stereotypical portrayal of the Inuit hunter. The cartoon resurfaced on a February 2002 airing of The Looney Tunes Show on Cartoon Network (in an installment that showed nothing but Chuck Jones cartoons due to the director's then-recent death), with only one edit: After Bugs finds out from the penguin that the days and nights are six months long in the Arctic, Bugs' line about not having to return to work until July 1953 is edited. When the cartoon aired again on a 2002 "June Bugs", wherein all the Bugs Bunny cartoons are shown in alphabetical order, both the 1953 line that was cut when Cartoon Network first showed this cartoon and the "Eskimo pie-head" line that was cut from the syndicated Merrie Melodies Show were edited out of the new Cartoon Network version.
Frigid Hare is 7 minutes long.
Frigid Hare was released on October 7, 1949.
Life with Father
During What's Up Doc?, Bugs is seen throwing away many scripts he's considering, one of them including Life with Father. Bugs predicts: "Eh, this will never be a hit!" In reality, the play was a big success, with over 3,000 performances and a rather lengthy run (from 1939-1947), making it the longest running non-musical on Broadway so far.
Frigid Hare - Title
The title of this short can be seen as a simply play on "frigid air" and/or on the refrigerator brand called "Frigidaire".
