There are some people are so afraid of committing mistakes and suffering from its consequences, and Marvel Cinematic Universe producer Kevin Feige is no exception. In fact, he was so scared of the mistakes he made in producing the first X-Men movie that he was certain that it would mean the end of his career, which was only starting.

This is what he revealed to Cinema Blend when asked about Avengers: Age of Ultron, the 26th feature film he produced for the studio. His success then and now has come a long way, and it would not have been possible if the studio lost faith in him early on. But it was not the case.

"Things come out for a reason. The very first film I ever worked on was X-Men 1. We went to go see the two hour 20 minute first version of that movie and I thought, my career is over before it starts. It's over. I didn't understand the process back then," he said.

The two hour and 20 minute film was never shown to audiences, of course, but it was heavily cut down post production. As a result, the first X-Men film was only 104 minutes long, but both critics and audiences alike loved it, and the first X-Men movie received tons of praises.

The next movies Feige went on to produce have been longer since his first attempt, and the producer believes it all depends on the stories. It also helps that people have developed a deeper appreciation for superhero action flicks, so they do not mind sitting through two hours of movie time.

The new movie Av engers: Age of Ultron is two hours and 30 minutes long, and Feige even teased that the home video release will be even longer.

"It always is that the movie is as long as the movie wants to be. I think there will be some deleted scenes that we put out on home video on this one," he said.

There are some differences in the new movie as well, the first being that Stan Lee's cameo will be longer, and the next is that there will be no post-credits scene as expected.

Sitting through the whole credits scene has been a relished tradition among Marvel fans, who are eager to get a glimpse of the next big Marvel villain or something similar. But after the highly popular shawarma post-credits scene from the original Avengers films, producers decided that there is no way they are topping it.
