Groundhog Day Useless Trivia

Stephen Tobolowsky, who played Ned Ryerson, was an Honorary Grand Marshal of the real-life Groundhog Day, as was Bill Murray and Harold Ramis. He also did the whistling belly button trick on stage.

This scene, and Phil's response of giving a fast-food order to the police, was supposedly inspired by a real incident with comedian Paul Lynde - who also asked for a cheeseburger before his arrest.

Yes, that's Michael Shannon - best known for playing General Zod in Man Of Steel and Nelson Van Alden in Boardwalk Empire. This was his first on-screen role.

Early drafts of the screenplay had it that Phil was trapped in the time-loop by a scorned lover. This was eventually cut from the final script.

No-one knows how long Phil was trapped in the time-loop. Some estimates put it at 12 years, others say 34 years. Harold Ramis, on the film's DVD commentary, believes it to be around 10 years.

Bill Murray was bitten twice by a groundhog during filming. The bites were understood to be quite severe.

The film wasn't made in the real Puxtsatawney, but in Woodstock, Illinois. Not only that, there's a plaque at the exact spot where Bill Murray put his foot in the puddle.

The poem Phil quotes isn't actually a poem - it's a song by Jacques Brel, called La bourrée du célibataire - or The Bachelor's Dance.
