"Something about the painted face, the fake smile," Depp told reporters while promoting Sleepy Hollow. "There always seemed to be a darkness lurking just under the surface, a potential for real evil."
Combs is also said to suffer from clourophobia. But he has repeatedly denied that his performance contracts call for a "no clown" clause, perhaps because it doesn't fit his bad-boy image.
Several years ago, Depp purchased a painting by John Wayne Gacy, the children's clown turned serial killer who tortured and killed 33 boys and young men.
The painting was a self-portrait of Gacy as "Pogo the Clown."
"They told me when I got it that the proceeds went to a charity or to the victims' families or something, but I found out that wasn't the case," Depp told the San Francisco Examiner.
Depp still finds clowns vexing. "Something must have happened when I was a kid," he recently told Entertainment Weekly. [Next: David Gest] 4. David Gest: Phonophobia
Life is a cabaret of legal trouble for Liza Minnelli and her estranged husband David Gest. Earlier this year, he sued her for $10 million, claiming he was a battered husband.
Days later, she sued for divorce, claiming he was "cruel and inhuman" to her.
The 50-year-old Gest claims he's in constant pain from beatings during the 15-month marriage. The show business producer claims to be taking 11 different medications a day, some more than once, for headaches, nausea, hypertension, scalp tenderness, insomnia — and phonophobia.
Phonophobia? Minnelli might assume that must be Gest's fear of being phony. After all, she denies all the allegations of violence.
However, phonophobia is the fear of using a telephone and, especially, the fear of the sound of your own voice.
While it's unusual grounds for divorce, Gest's lawyer Raoul Felder told reporters, "I have enough grounds for 14 divorces here," he said. "We could divorce the entire Yankee team, including the bullpen." [Next: Christina Ricci] 5. Christina Ricci: Botanophobia
Here's something to put in Christina Ricci's Christmas stocking — a Weed Whacker. The 23-year-old actress admitted to British Esquire this summer that she suffers from a form of botanophobia — and we're not exactly talking about Attack of the Killer Tomatoes.
Ricci swears she's afraid of houseplants. "They are dirty," she said. "If I have to touch one, after already being repulsed by the fact that there is a plant indoors, then it just freaks me out."
Ricci's also not so keen on swimming pools: "I won't swim in a pool by myself because I think that somehow a little magic door is going to open up and let the shark out."
6. Roger Moore: Hoblophobia
Being The Man With The Golden Gun gave Roger Moore a nervous tic. The star of seven James Bond films was decidedly more shaken than stirred by his License to Kill firearms.
"The only acting I ever did was trying not to blink because as soon as I pick up a gun I start blinking," said Moore at a 1993 UNICEF fund-raiser.
In espionage, however, a nervous secret agent can hide under his bed and still tell his boss he's deep undercover. [Next: Alfred Hitchcock] 7. Alfred Hitchcock: Ovophobia Was Alfred Hitchcock, the master of suspense, chicken around eggs? To witness his ovophobia, just watch To Catch a Thief.
