That doesn't jibe with the Tommy Kirk page at IMDB:
From the bio: "However, in 1964, the Disney factory found out Tommy was gay and they immediately released him from his contract after finishing The Monkey's Uncle (1965)."
Personal Quote: "Even more than MGM, Disney [in the early 1960s] was the most conservative studio in town....They were growing aware. They weren't stupid. They could add two and two, and I think they were beginning to suspect my homosexuality. I noticed people in certain quarters were getting less and less friendly....In 1963 Disney didn't renew my option and let me go. But Walt let me return to do the final Merlin Jones movie, 'The Monkey's Uncle,' because those were moneymakers for the studio."
I was wondering about that just the other day how career paths can differ as to why Tommy Kirk fell into obscurity where Kurt Russell, the other boy star Disney was heavily marketing at that time went on to do well.
