Elvis and Steve Forrest

Did Elvis and Steve Forrest get along when they were filming Flaming Star? In the movie they worked well together and came across like they were brothers. That dramatic scene between them in the end was one of their best together. To tell you the truth, Elvis was even great with John McIntire and Dolores del Rio. It really seemed like they were his parents. I remember the scene when Elvis goes outside to take care of a guy that was going to attack his mother. It was a nice scene when Elvis comes back in and his mother could see he was fighting and they hug.
