9. The famous knife trick in Aliens was sprung on actor Bill Paxton by co-star Lance Henriksen. From Film School Rejects:
According to Henriksen, Paxton had no idea he was going to be part of the “knife trick” scene until it came time to shoot it. Henriksen felt the scene needed something extra, so he and Cameron decided on set Bishop would hold Hudson’s hand down and perform the trick on him. Henriksen also remembers a long night of drinking after shooting this scene followed by a reshoot of the scene, as it looked too fake when they sped the footage up. He accidentally caught Paxton’s pinky with the knife on this reshoot.
