Darkman II: The Return of Durant (1995)

Revealing mistake: Near the beginning, when Westlake is experimenting and his mask melts, you can clearly see that the mask is not really melting, and is just covered with suds while a "melting" sound effect plays.

Doctor: Chow time, Doc.
Dr. Alfred Hathaway: So, what are we having this evening? Lobster florentine. Beef wellington. Perhaps grilled ahi on a bed of Belgian endive.
Doctor: No, your old favorite, Doc.
Dr. Alfred Hathaway: I hate meat loaf.

Trivia: In the original film, Westlake/Darkman was played by Liam Neeson, whereas in this sequel the character is played by Arnold Vosloo. However, if you pay close attention, you can see that several shots of Liam Neeson from the first movie were used as stock-footage in this film. (Ex. the opening flashback is a mixture of both Neeson and Vosloo footage cut together, and at least once you see a dramatic close-up of Darkman's eye which is a shot of Neeson taken from the first film.).
