James Gunn returning to write, direct 'Guardians 3'

"Guardians of the Galaxy Vol. 2" has not hit the theaters yet, but Marvel has set James Gunn to return to write and direct a third installment.
Gunn announced the news on his Facebook page on Monday.
"So, after many months of ruminations and discussions, I know the answer. I could save this answer for the first, random interviewer to ask me during the press junket but instead I thought I'd share it with the most important people in the Guardiansverse - you, the fans.
"...You have been so incredibly supportive and enthusiastic over the past five years, it has moved me to tears on a regular basis. So, yes, I'm returning to write and direct Guardians of the Galaxy Vol. 3," he wrote.

Chris Pratt, Zoe Saldana, and David Bautista currently star, and it seems likely they would return to reprise their roles. Kevin Feige is producing for Marvel.
The first installment was a huge hit for Marvel, grossing USD 773 worldwide.
