The 76-year-old actor - who stands at 5' 10" -

auditioned for the title role in the 1978 superhero movie

joked that had he been successful in his bid for the

part that eventually went to Christopher Reeve

he wouldn't have looked good in the costume.

He said: "I auditioned for Superman. I’d have been the world’s shortest superman…

I don’t look good in leotards at all!"

Meanwhile, the Golden Globe-winning star

who has daughters Scarlet, 20, Sistine, 24, and Sophia, 26

wife Jennifer Flavin but was previously been married to Brigitte Nielsen

went on to add that he is hoping to get his own reality show to follow his family life while he is still "relevant."
