Question

about 2 famous outlaw gangs /
also name the movie

Hint - The Long

Answer 1

...that would be director Walter Hill's "The Long Riders", from 1980; if I recall correctly (trying to do this without cheating), actors Stacy and James Keach portrayed the outlaws Frank and Jesse James, the Carradine brothers (David, Robert and Keith) played Cole, Bob and Jim Younger, and and Dennis and Randy Quaid were the Miller brothers (I forget their first names).

Answer 2

"The Long Riders" has James and Stacy keach as Frank and Jesse James; the Carradines as the Youngers; and Randy and Dennis Quaid as the Millers.
