Corrected entry: Zsasz says that he had a hand of four sixes during poker. He then says Penguin beat him with a straight... 3, 4, 5, and 6. How could Penguin have a 6? Even if he was cheating that would have invited comment, rather than the legitimate loss for Zsasz it seems to be.
Revealing mistake: When Clayface disguised as Joker is holding Talia hostage in the movie theater, they are both standing on stage in front of the screen with a movie playing. However, they are not casting shadows on the screen. Also, no shadow appears on the screen when Clayface takes on his true form.
Professor Hugo Strange: I feel I should thank you, capturing Bruce Wayne is so much easier than Batman.
Trivia: At the theater Clayface is watching "The Terror" a movie starring Jack Nicholson, who played the Joker in 1989's Batman.

Suggested correction: More likely, this is a reference to Clayface's origin in the comics, where he was an actor who starred in a film called "The Terror," then dressed as its killer and killed the cast and crew of a remake set to be made without his involvement (his shapeshifting powers coming later into his character's life). This is evidenced by how the film on the projection screen appears to be a black and white film from the 30s-40s, matching Clayface's first appearance in comics.

Correction: That's the point of this dialogue. Penquin's reputation is such that, even when he is blatantly cheating, no one dare call him on it. Not even a psychopathic serial killer like Zsasz.
