Costner was 34 when field of dreams came out in 1989. What does the fact that he was 15 in 1970 have to do with a movie that came out 20 years later?
I can’t see John Ritter in that role at all.
My only point being, with all due respect, was that I thought Costner was a little young to play someone who rebelled against his father in the 1960s. That is why I would have been curious to have seen how Ritter, Hurt, Murray, or even Ford would have played the role as they would have been at about that coming of age in the 1960s period.
