Julia Louis-Dreyfus' original (before being corrected) Hollywood Walk of Fame star
edit:
Most of the people whose names have been misspelled in film credits have gone on record stating it was not their idea, thus not an "alternate" or "variant" spelling.... so no "guess work" involved, it is a typo...others, like Edgar Allan Poe, who died in 1849, aren't around to say so.
Here's Christopher Walken at the 2012 TIFF:
Question: Christopher, I’ve always wanted to ask, how did you feel when they misspelled your name in the credits of Annie Hall?
Christopher Walken: You know, that’s so interesting.
Catherine Keener: I never knew they did that.
Christopher Walken: It’s V-L-A-K-E-N.
Catherine Keener: No, they did not.
Christopher Walken: Christophe Vlaken. And that’s in the credits of Annie Hall.
Catherine Keener: [Laughs] They did not.
Christopher Walken: Absolutely, if you see the movie, it’s still there, right?
Catherine Keener: I’ve seen the movie 20 times.
Christopher Walken: It’s Christopher without an R and it’s V-L-A-K-E-N. But, I mean, these things get checked by 1000 people.
Catherine Keener: Was Woody Allen f*cking with you?
Christopher Walken: Maybe he was. No, but that is a very odd thing. I thought I was the only one who knew that. And I remember at the time, my agent called and said, “Can you fix that?” And they said, “No, it’s on 10,000 prints.” I could’ve sued somebody.
