Jemma Dallender had a body double for her love scene with Steven Seagal. This was accomplished with tricky editing, careful camera work, and having the double shown only from behind.
Steven Seagal gained 60 pounds for his role in "contract to kill". nobody asked him to.
When Steven Seagal arrived on set, the director initially told Steven Seagal that they were delaying the film due to his considerable weight problem, which saw his monster-like stomach poking out his shirt. It wasn't until Seagal got so mad that he tried to eat the director's fingers and sit on the writer that they decided to digitally edit him to make him appear noticeably less obese. Many people who worked on the film thought Seagal was like a fussy baby who wanted attention, food, and emotional support.
