He is the father of popular actor Michael Douglas, who wound up turning down the role of John Rambo.
He was originally to play Colonel Sam Trautman in First Blood, but backed off the film several weeks into production because he was unhappy with the ending (he wanted Rambo to die), and Richard Crenna was hastily cast at the last minute, having only one day to prepare for the role after enthusiastically reading the script. Because it was so far into production, there are photos of Douglas in costume as Trautman and even ads with Douglas's likeness on them.
