Jennifer Garner avoids co-starring with JLo.

Jennifer Garner reportedly turned down a role in the movie version of Dallas after she found out that Jennifer Lopez had signed on to star in the film. Garner was in negotiations to play the role of Pamela Ewing when she discovered that husband Ben Affleck’s ex had been cast as Sue-Ellen. “Jennifer Garner was really keen to be in Dallas, but I think she felt there would be a bit of a strain between them on the set and that could have led to awkward situations,” a source told a British paper. “Both are totally professional, but there might have been a certain ‘atmosphere’ and Jennifer Garner didn’t need to go there.”
