The INSIDER Summary:

  • Vin Diesel and Bradley Cooper voice Baby Groot and Rocket Raccoon in “Guardians of the Galaxy Vol. 2.”
  • The characters aren’t all CGI.
  • They’re really on set, too.
  • A combination of visual effects, actor stand-ins, and dolls bring the characters to life.

“Guardians of the Galaxy Vol. 2” is now in theaters and while you may easily notice Chris Pratt, Zoe Saldana, Dave Bautista, and more of the film’s first cast in the sequel, two of other familiar faces return to lend their voices to the cast.

“Fate of the Furious” star Vin Diesel and Bradley Cooper return to bring the adorable tree creature Baby Groot and feisty raccoon — or trash panda — Rocket to life.

While we see the two in the film like this:

They actually look a bit different on set. 

Director James Gunn’s brother, Sean Gunn, fills in for Rocket Raccoon on set. Here’s how he looked while filming the first movie.

If Sean Gunn looks familiar, it’s because he’s doing doubletime as both the onscreen Rocket and Yondu’s Ravager sidekick, Kraglin.

Special effects makeup designer David White also made two life-size versions of Rocket Raccoon along with a bust of Groot as aids for visual effects and lighting for the first film.

“The reason the filmmakers wanted these is because they take them onto the set and they put them in little chairs and they put them next to the doors and it gives them a good indication of where visual effects needs to pick up and whether Rocket can actually reach certain things or use certain devices,” White said in the first film’s production notes. “Also they offer them up to the camera at the end of the shot and it just gives them an extra little hint of the lighting because they’re actually painted exactly as they want.”

Behind-the-scenes, Bradley Cooper gets rigged up to voice the character. He’s wearing a suit to capture his movements while performing.

In the first film, polish actor Krystian Godlewski wore a motion capture suit to give the physical cues for Groot and provide a model for actors to look at while filming.

Yes, that is a bust of Groot’s head atop a blue suit.

In the sequel, a miniature version of Baby Groot was used on set to stand in for the character. 

Visual effects supervisor Chris Townsend and his team built a ten-inch maquette of Baby Groot to add to scenes to aid with creating a CG character on screen.

You can spot Baby Groot in b-roll footage released for the sequel. Here he is standing near Drax during filming of the movie’s opening fight sequence.

Unlike Cooper, Vin Diesel comes to work in his regular clothes to voice Baby Groot.

In case you’re wondering, Diesel did do the voice for Baby Groot in the sequel. According to Entertainment Tonight, very little modification was done to Vin Diesel’s performance for Baby Groot. Diesel has been imitating cartoon characters since he was young.
