In The Closet
From one taboo topic to another, gay actors stayed in the closet as fiercely as possible as they were afraid of public disappointment. Robert Reed, aka Mike Brady, was no exception. Florence Henderson had noticed early on that Reed was uncomfortable during romantic scenes, eventually in private he admitted the truth. As a result the pair worked around it, rehearsing kissing and hugging off-camera, in order to appear like a more natural couple when filming. Bonus fact: the entire cast kept Reed’s homosexuality a secret, even after his death.
