I know the only movie anyone cares about this weekend does not have Meryl Streep in it. Still, there is this singing dancing musical thing she’s doing, and it’s opening Friday. If you’re looking for something to do after The Dark Knight, and you live in California, we’ve got a way for you to see and sing Mamma Mia! for free.

Universal Pictures is planning a great event in Glendale, California at Pacific Glendale 18. To celebrate the opening day of Mamma Mia!, this Friday they’re hosting a Singing Contest. The first 100 people to show up at the screening get in for free, they show the movie, and everyone does some singing.
