Sometimes, even professional actors have trouble nailing a take. While Tom Holland and particularly Jake Gyllenhaal are well-seasoned actors with a good deal of professional acting experience, the scene where their characters, Peter Parker (Holland) and Quentin Beck (Gyllenhaal), shake hands and formally introduce themselves proved to be unexpectedly troublesome.
While it’s a fairly simple scene in its execution (or, at least, you would think), the actors had a difficult time keeping the giggles away, to the point where take after take was botched by their chuckles. According to Gyllenhaal, the actors needed at least 40 takes in order to get the scene right. Even then, it wasn’t easy. Gyllenhaal said this scene in the final cut is basically only a millisecond long because that’s the only useable footage available. Sometimes, even professionals can’t keep it together.
