Jennifer Aniston is Flat

Jennifer Aniston and costar Owen Wilson film scenes together on Thursday on the Miami, Florida set of their new movie, Marley & Me.

The film is about a family learning important life lessons from their adorable, but naughty and neurotic dog, Marley (a labrador retriever). It’s based on the memoir by John Grogan, played by Wilson.

In this scene, Aniston‘s character, Jennifer Grogan, suffers a flat time and Wilson tries to fix it. Unfortunately, he can’t and a few highway patrol men swoop in to rescue them.

Marley & Me is set to open Christmas Day 2008.

The rumor mill is spinning than Aniston is romantically involved with Canadian cutie Brian Bourma, working on the set of her other movie, Traveling.
