Lopez is attached to play Sue-Ellen in the movie, with John Travolta as her husband, J.R. Had she taken the part, Garner would have been Lopez’s sister-in-law, having married her husband’s brother. No doubt, the set would have been quite tense, as Garner got from Affleck what Lopez never could: marriage and a baby.

A source told British newspaper, the Daily Mail, "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. Both are totally professional, but there might have been a certain 'atmosphere,' and Jennifer Garner didn't need to go there."
