Guardians of the Galaxy director James Gunn has been on Periscope to offer updates on the Marvel film's sequel.
Answering fan questions on the live-streaming video app, he confirmed that Karen Gillan's alien villain Nebula - the adopted daughter of Thanos - will be back for the follow-up.
Gunn added that he has come up with a way for the former Doctor Who star to play the role without shaving her head.
The director also revealed that he is "very, very far along" with the script for Guardians 2 having completed 70 pages.
"I turned in my treatment," he said. "I'm going to meet about it on Friday and we will start working on the screenplay next week."
On the filming location for the sequel, Gunn confirmed that the production would be moving away from London to Pinewood Atlanta Studios, and that the shoot would commence in February 2016.
