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.

Robert G. Durant: I abhor violence, especially when it doesn't make me money.

Trivia: "Darkman II" was the first direct-to-video release for Universal Studios. It was granted a larger budget in comparison to many other subsequent direct-to-video releases and had a decent marketing push, as Universal was testing the waters for movies exclusively made for the video market. The gamble with a success, with Universal continuing to release direct-to-video (and more currently, direct-to-Netflix) releases well over twenty years later.
