Audio problem: When Selina returns home from work the first time and Miss Kitty comes in through the window, Selina pours some milk into the cat bowl and Miss Kitty begins to lap the milk (out of shot). Then, without a break in the lapping, Miss Kitty meows again as a cue for one of Selina's lines, but the lapping sounds continue underneath the meow. It's an open-mouth meow, too, and, as far as I know, no cat can both meow and drink at the same time. (00:22:45)
Audio problem: When Selina is pushed from to window, her scream doesn't match her mouth movement. (00:27:05)
Audio problem: When Oswald holds Catwoman's cat down to the bed while she puts his bird in her mouth, hisses and meows are heard from the cat, but it doesn't open it's mouth. (01:03:25)
Audio problem: On the batmobile screen, the Penguin says "Just relax " but when Batman plays the Penguin's audio back on the tannoy speakers, it is "Hey, just relax " (01:20:30 - 01:26:00)
Audio problem: The Batmobile is supposed to be powered by a Jet engine. The sound in the sequel is dubbed rather flawlessly except for two brief instances when you can hear the 8 cylinder piston engine.
Suggested correction: Can you be more specific as to what point in the film these errors occur?
Audio problem: When the mayor's baby is first stolen, the audience gasps in a very fake way. When the Penguin reveals his plan to steal the first-born sons to the party members later in the movie, they gasp the exact same sound effect. They actually do it a third time, later in Penguin's speech, but it's very quiet.
