He never knows what he’s gonna get.

Tom Hanks has so many memorable movie lines he can’t quote just one fan favorite.

“I’m kind of lucky that I have a lot of catchphrases that everybody just yells at me,” he told The Post.

The two-time Academy Award winner fired off a list of the top contenders.

“‘Run,’ ‘I wish I was big,’ ‘Wilson,’ ‘Brace for impact,’ ‘Houston, we have a problem,'” Hanks, 69, said of the classic quotes from “Forrest Gump,” “Big,” “Cast Away,” “Sully” and “Apollo 13.”

The A-lister, who spoke to The Post on the red carpet for the opening night of Broadway’s “Celebrity Autobiography” — where his wife, Rita Wilson, took the stage — explained why he will never pen a memoir.

“Because I have too many family members who would literally camp out on my doorstep with torn-out copies of the book with highlights that said, ‘You are so wrong about this moment.’ I don’t want to be in that position,” he said.

While the Los Angeles resident was in the Big Apple, he visited Citi Field to watch the Mets take on the Yankees in the Subway Series.

Hanks said he didn’t mind when Mr. Met came out to visit him dressed as Wilson, his volleyball companion from “Cast Away.”

“Here’s the deal. I was a guest of the Mets. I didn’t pay. They gave me great seats. If they want to send Mr. Met down and talk to me on the jumbotron, I believe that’s how I earned their good graces,” he said.

He is currently gearing up for the June 19 release of “Toy Story 5,” where he reprises another one of his beloved roles — the voice of cowboy doll Woody.

The father of four said he would have never imagined that he and his co-star Tim Allen, who voices spaceman action figure Buzz Lightyear, would still be working on the franchise 35 years later.

“None of us could quite believe that. You know, Tim Allen and I walked in on sort of like this goofy kind of lark into a soundstage recording studio at Disney Studios in 1991, and we are still going into that very same soundstage recording studio … and we are still doing something that we cannot quite believe, that is unfathomable,” he said.

“And we pinch ourselves that we get to be a part of something that is so long lasting.”
