‘Avengers 4’ star Karen Gillan explains how Marvel prevented spoilers

"I don't know what this movie's about."

Karen Gillan has revealed that Marvel went to extreme lengths in order to prevent Avengers 4  spoilers leaking from the set.

The former Doctor Who star has played  villainous alien-cyborg Nebula in Avengers: Infinity War and two Guardians of the Galaxy movies. She returns as the blue character in the highly anticipated, and as yet un-named, Avengers 4 film.

Speaking to Shoot This Now podcast, she said:  “We didn’t even get a script, there was no script. Just my scenes. I’d sometimes get them just in the morning, do them, hand them back over at the end of the day.

“The directors would fill us in on everything that we needed in terms of context, but still, I don’t know what this movie’s about.”

She was careful to not reveal the title of the upcoming film. Fellow cast member Mark Ruffalo recently teased fans that he’d accidentally revealed the sequel’s title during a recent appearance on Jimmy Kimmel Live!

“I trust that you will cut my spoiler slip on the show tonight. That was “off the record” homey. Please don’t get me in trouble with Marvel (Barry) again. DM me back”, he wrote.

Ruffalo is known for letting the cat out of the bag – having inadvertently revealed the Infinity War ending a year before it was released.

It was recently revealed that 13 Reasons Why star Katherine Langford joined the Avengers 4 cast. Langford – who was nominated for a Golden Globe for her starring role as Hannah Baker in the Netflix show – has reportedly already filmed scenes for the Marvel movie.

Gillan is expected to play Nebula in the delayed Guardians of the Galaxy 3. The film’s future has been uncertain since Disney fired director James Gunn was fired by Disney on July 20 following the re-emergence of a number of his old tweets, which made offensive jokes about paedophilia and rape.

Asked about the future of Vol 3, she said: “I actually don’t know, is the honest answer. I feel like they’re talking about it, and trying to figure out what the next best move is.

“I’m hoping that it all comes together and we get to tell the story, because it will be nice to continue it.”

Disney’s decision to remove Gunn from his role as head of the franchise he created prompted a wide backlash, with the stars of the films signing an open letter in defence of Gunn a week after his termination.

Avengers 4 will be released in the UK on April 26, 2019, and in the US on May 3, 2019.
