Garry Marshall was filming the Michelle Pfeiffer/Al Pacino romance Frankie and Johnny in the same studio as Star Trek VI. He decided to take advantage of this fact when a key shot relied on Al Pacino’s complete surprise upon opening a door and seeing who was on the other side. Marshall asked Nicholas Meyer if he could borrow his two leads for a few minutes and had them waiting on the other side of the door, in full costume.

Pacino, of course, delivered.
