STAR TREK: FIRST CONTACT (1996)
Cromwell went all-out to perfect his performance as a scientific genius who enjoys his liquor.

"For my dancing sequence, I wanted to [do something similar] to Nicholson in Easy Rider when he takes the drink and flaps his arm up and down. So I bought myself a fifth of Jameson's, took a good belt, and went to rehearsal. Well, it seemed to go very well. So while they were setting up for the shot I took another belt. I must have done that four or five times, so by the time I was dancing, I was having a lot of fun. It was a method performance. [laughs]"
