The "Gone Girl" actor said while in a scene with the "Toy Story" star where his character — as Santa  — comes down the chimney and frightens Sara, Allen made things difficult by complaining about her performance to a producer standing a few feet away from her.

"I basically hear him, he goes, 'You gotta tell her to stop stepping on my lines,'" Wilson said. "The producer turns to me with horror on his face and has to walk one foot to me and he goes, 'Tim would ask that you stopped stepping on his lines.'"

She continued: "(He) never made eye contact, never said anything. It was so uncomfortable."

Early this year, Allen was accused by Pamela Anderson of flashing her on the set of "Home Improvement."

In her January memoir "Love, Pamela," according to Variety, Anderson discusses booking the role of Lisa the Tool Time Girl on the family sitcom. Allen led the cast as Tim Taylor in all eight seasons of the hit ABC comedy. Anderson appeared as Lisa for 23 episodes from 1991-1997. Debbe Dunning replaced the role of Taylor's assistant in the show's third season.

While the role gave Anderson her first taste of major fame, the actress writes about an on-set interaction she had with Allen on the set of the ABC series.

"On the first day of filming, I walked out of my dressing room, and Tim was in the hallway in his robe. He opened his robe and flashed me quickly — completely naked underneath," per an excerpt from the book first published by Variety. "He said it was only fair because he had seen me naked. Now we’re even. I laughed uncomfortably." 

In a statement provided to USA TODAY on Jan. 22 by Allen's representative Marleah Leslie, Allen denied Anderson's allegation. "No, it never happened. I would never do such a thing," Allen said in the statement.
