Marvel Universe movies have a post-credits scene because Kevin Feige is a "film nerd".
Kevin Feige
The studio boss admits he never wanted his cinema trips to end when he was a youngster so would stay in his seat until he had to leave, and felt adding in more footage after the titled rolled was a good way of thanking those just like him.
He said: "I always liked that sort of thing, whether it's 'Ferris Bueller' or 'Masters of the Universe'. As a film nerd, I never wanted it to end. I didn't want the experience...no matter how good or bad the movie was, just the experience of being in the movie theatre, I didn't want to end.
"So I would always sit through the credits. My Mom would do that, too. Would read all the names and think it's so interesting what everybody does.
"So I would always sit through all the credits and you're about two-thirds of the way through and it's like oh should I go? Well maybe there's, I mean, that one time there was something in that movie. Maybe there'll be something on this movie. And there never was. Almost never was.
"So when I started making movies, I'd be like that'd be fun to do."
The first post credits scene for Marvel came with Samuel L. Jackson's appearance as Nick Fury at the end of the first 'Iron Man' film, and it was placed at the end because Kevin worried it would be too "distracting" for audiences if it was part of the main feature.
He told /FILM: "The Sam Jackson Nick Fury idea came about during production. You've heard this story, Sam was willing to do it. We shot it secretly. It leaked the next day.
"But we didn't wanna put it in the body of the film 'cause we thought it would be distracting.
"So we thought we'd put it at the very end of the credits for people who like me when I was a kid could be rewarded for staying and if you stayed that long, you probably knew who Nick Fury was. And what that meant.
"And then it became a tradition and then it really varies. Sometimes we conceive of the tags during development, sometimes during production, sometimes during post-production."
