Elvis continued to practice karate, never met Bruce though.
Bruce was McQueens teacher but they had an odd, egotistical relationship. McQueen was pretty competitive, Bruce asked for his help getting a film made, McQueen told him he loved him but no, he wasn't in the star making business. Bruce left his house shaking his fist at the house saying, "i'll be bigger than him". That carried on until Enter The Dragon when Bruce bragged about being in a hollywood film, McQueen sent Bruce a photo signed, "To Bruce, my biggest fan" which of course pissed Bruce off. Then Bruce dies and McQueen is one of the speakers and one of the pallbearers.
Like I say, why be an asshole, especially when you will no doubt live to regret it.
