Mohawk hairstyle
The script continued to change during filming. When Tobolowsky arrived for his first scene, he was handed a new script. He estimated that about a third of the script was different from his original copy. For example, early in the film, Phil ends his first loop by breaking a pencil to see if it is repaired the following day. A more elaborate scene was filmed in which Phil spraypainted the walls of the room he wakes up in, destroyed objects, and gave himself a Mohawk hairstyle. The scene took three days to film and was costly; Ramis discarded it for something deemed quieter, simpler, and less manic. The revised script also featured more of Phil's misadventures, and his suicide attempts were set closer to the film's end. These scenes were moved forward in favor of a long third act showing Phil embracing life.
