The Woody actor has opened up about recording his last scene for the upcoming Pixar sequel, admitting it was a "moment in history".
"It was the first time that we were going to be recording the end of the movie, and Toy Story  is going to have an impactful ending," he told The Chris Evans Breakfast Show.
"The way you record Toy Story, you're in a room with the team that has created it. When I went in for my last day of recording, I wanted to have my back to them, because usually you're facing him so he can look right up and you can talk about it.
"But I didn't want to see them and pretend they couldn't see me. When I realised what they were going for, I realised, 'Oh, this is a moment in history'."
Oh gosh. If he cries that means we're going to cry too.
Allen, who voices Buzz Lightyear, said back in September of his own emotional experience: "I gotta resist getting emotional. I don't want to give it away, but this is an incredibly great story.
"It is so emotional, it's so funny, it's so big, the idea they've come up with, I'm startled. I couldn't even get through the last scene.
"I would love to be a Washington leaker. I just can't do it. I can't give any more away. They've got great characters but a couple of scenes toward the end were really hard to get through."
Toy Story 4 will be released in UK and US cinemas on June 21, 2019.
