WALL-E has done very good things for Disney and for Pixar. One party that also profited from Pixar's latest hit is Jerry Herman, the composer of Hello, Dolly!. Two songs from Hello, Dolly!, 'Put On Your Sunday Clothes' and 'It Only Takes a Moment', play a major role in WALL-E.
Due to the prevalence of Hello, Dolly! in WALL-E, a Broadway revival has been considered. There has already been a huge increase in the videos and DVDs and CD rentals/purchases. Here is a link to the article discussing this.
Many find Hello, Dolly! to be an odd choice for WALL-E. According to Stanton,
"After discovering 'Put On Your Sunday Clothes,' I started exploring the other songs in the play, and when I found 'It Only Takes a Moment,' it just became this godsend because I was always looking for ways to tell the story without the need to use conventional dialogue. This song became a great device for showing WALL-E's interest in what love is, and it gave him a way to convey his love for EVE. I happened to have read somewhere that holding hands is the most intimate public display of affection, which led to the idea of WALL-E learning that action by watching the movie. Suddenly I was desperate: ''I've gotta get a copy of Hello, Dolly! Please, please, please let them show these two lovers holding hands!'' And they were! I took that as a sign that it was meant to be to have these songs in the film because Hello, Dolly! was suddenly helping me tell the story."Here is the link to the interview with Stanton about Hello, Dolly!.
