Even a runtime of 149 minutes seemed like it wasn't long enough for fans of the Avengers movie franchise - viewers flocked back to cinemas for repeat viewings of the series' latest installment, Infinity War, clearly wanting to get as much as they could out of the hotly-anticipated film.
If that's the case, fans will be pleased to know director Joe Russo could have a pretty lengthy run time planned for the follow-up, currently in production under the working title of Avengers 4.
In an interview with Collider, via the Express, he said: "I'll say it could easily be a three-hour film."
That's right, three whole hours of Avengers action could comfortably await us. Maybe a good time to reintroduce the interval to cinemas, eh?
Joe explained: "But I think that, you know, we're very hard on the material. We like it to play at a certain pace. Uh... I... you know, I'm sure that we'll squeeze it.
"I can't imagine... We have a whole year of work left on that movie. I do think it will be longer than Avengers 3 [Infinity War], but it's clearly impossible to say."
A whole year to wait for the next outing - it's almost an unbearable thought, especially after (spoiler alert!) Thanos disintegrated some of our favourite characters in a click of his fingers, the bastard.

At first glance a runtime of 180 minutes may sound fairly long to endure, but in reality lengthy films aren't that uncommon.
For those that aren't overly fond of a long runtime it may be best to think back to 2003 when The Lord of the Rings: The Return of the King had an impressive length of 201 minutes - and, no, this wasn't the amazingly long extended edition.
In more recent years Martin Scorsese teamed up with Leonardo DiCaprio for The Wolf of Wall Street, which was bang on three hours long.
Marvel aren't the only company to be commissioning longer runtimes for their fan faves - HBO announced last year that the eagerly-anticipated season 8 of Game of Thrones would see each of the six episodes reaching feature length.
During season 7, episodes ran at an average of 68 minutes, while the season finale 'The Dragon and the Wolf' ran to 80 minutes.
For fans out there who feel hard done by when their favourite show or film finishes, this can only be good news.
Plus, if you think about it in a different way, yes you'll be sat in that cinema seat for longer, but for the same price ticket you paid for Infinity War, you'll get even more for your money watching Avengers 4 - bonus!
