Benedict Cumberbatch has teased what fans can expect from Avengers: Infinity War when it hits screens next year.

The movie will be the third Avengers outing and will unite famous faces from across the entire MCU, including appearances from the Guardians of the Galaxy and Thanos (Josh Brolin) – who will be the movie's big bad.

Guardians aside, Infinity War will also mark the first Avengers outing for Ant-Man (Paul Rudd) and Doctor Strange, following Cumberbatch's role in the 2016 movie.

Avengers: Infinity War will be released in April next year and filming has already wrapped. But what can Cumberbatch tell us about the movie so far?

"It's ten years coming," he told press including Digital Spy. "It's just a huge, huge, huge amount of work, huge amount of storylines and it's all sort of pointing to this confrontation.

"It's amazing to part of it even though I'm late to the party, it's very cool one to be part of it.

Hmm. Expect a lot of storylines to merge and maybe some even to conclude, if rumours about significant cast deaths do indeed turn out to be true...

Of course, Cumberbatch's casting in the Avengers film naturally led fans to question why Doctor Strange decided not to join the superhero team until their third world -saving outing.

Well, Marvel's Kevin Feige had a pretty compelling answer for that.

"There are people inhabiting the same world that are stopping buildings from falling down, robots from doing this, aliens from doing that – these people in this movie are stopping inter-dimensional forces from wiping out all of reality," he told Collider.

"So although it doesn't necessarily come up, we've always assumed that the sorcerers have bigger fish to fry when they hear there's something in a city or there's a bank being robbed."

Mystery solved.

Avengers: Infinity War will be in cinemas from April 25, 2018. Watch a trailer for Thor: Ragnarok, the next instalment in the MCU, right here:
