Jennifer Garner Films Dallas Buyer's Club in New Orleans

Jennifer Garner was on the set of her new film, The Dallas Buyer's Club, in New Orleans yesterday. Jen was in costume, as was a gaunt Matthew McConaughey, who shed 30 pounds to play the role of an AIDS patient. Jared Leto reported for scenes as well, in drag as his character. Earlier this week, Jen caught a flight out of LAX to begin work on the project, leaving her husband, Ben Affleck, and the kids back home in LA.

Matthew, though, is joined in Louisiana by his spouse, Camila Alves. Camila, pregnant with their third child, has been spending time with their little ones, Levi and Vida. On Tuesday, Camila met up with pal Sandra Bullock and her son, Louis, to watch the Warren Easton Charter High School marching band perform. The school is close to Sandra's heart, as she "adopted" it, providing financial assistance, after Hurricane Katrina. Sandra and Matthew have remained friends after dating in the '90s and both own homes in Austin, TX.
