Pratt, who plays the wise-cracking, morally flexible hero Star-Lord, shared some epic behind-the-scenes snapshots to commemorate his time on set.
"That's a wrap on #gotgvolume2. Went ahead and marked my territory at [Pinewood Atlanta Studios]. Any dog caught peeing on my hydrant will go to the pound." Pratt captioned of picture of himself kneeling next to a fire hydrant artistically modified to look like his Guardians character. Behind the hydrant there's an official-looking sign that reads Property of Star-Lord. Dogs beware."
Pratt also shared his thanks with "all the wonderful people in Atlanta/Fayetteville for your hospitality. God bless you."
Pratt later posted an on-set pic of himself and his stunt double, Tony McFarr, decked out in matching Star-Lord outfits, including face masks.
"Been working with Tony since Jurassic World. Love you buddy! Happy wrap!" the 36-year-old star wrote in the caption.
Pratt followed that up with another pic of himself and McFarr without the masks for "better view."
The hotly anticipated sequel wrapped just in time for next month's San Diego Comic-Con. Director James Gunn shared a video on Thursday announcing that the film would be represented at the massive convention, and promised to bring fans some awesome teases.
"We, Guardians of the Galaxy Vol. 2, are coming to San Diego Comic-Con this year," Gunn said. "We’re going to be there, I’m going to be there, Chris Pratt is going to be there, a bunch of the gang is going this year and we’re going to show you something pretty cool."
Gunn spoke with ET last year at the Hollywood premiere of Avengers: Age of Ultron in April, where he opened up about Vol. 2's soundtrack, and how it stacked up against the original's.
"I did feel a little pressure for the soundtrack because so many people loved it and we went platinum and all that other stuff. But I feel like the soundtrack in the second one is better. I feel like it's better, so I'm excited about it." Check out the video below to hear more.
