I hadn’t watched “Annie Hall” in years so I taped it, and while reading the credits was shocked to find that Christopher Walken’s name had a typo in it.
I Googled it and found he addressed the situation in an interview from 2012. Funny that either Walken remembered wrong how his name was misspelled or perhaps the credits were changed after printing but not changed enough? Anyway, the plot thickens. Fascinating to find he never got an apology and that it was never fixed!
Here’s the link to the interview — the question is about halfway down the page.
