Phil Tippett, the visual effects maestro who worked on Star Wars and the original Jurassic Park, might be working his sleight of hand on the upcoming fourth installment of the sci-fi dinosaur franchise.

Colin Trevorrow, the director of Jurassic World, suggested that Tippett may come on board on Dec. 17 via Twitter. He uploaded an image of Tippett holding on to a maquette of a T-Rex with the caption "welcome back, Phil."

Tippett was credited as a "dinosaur supervisor" in the first film, in which he was initially meant to use the go-motion technique which he has mastered for the Empire Strikes Back. But Steven Spielberg changed his mind and chose to go with CGI instead and Tippett supervised the animators.

Tippett won his first Oscar for his work on Return of the Jedi, in which he used stop-motion animation to bring the AT-ATs and tauntauns to life. 

Trevorrow has generally been very proactive about updating fans about all the developments with the film via Twitter. Recently, by way of a response to a fan query the director revealed that the new film will be a sequel and not a reboot. He suggested that the film will be set 22 years in the future.

The film will star Bryce Dallas Howard, Chris Pratt and Ty Simpkins.

The Jurassic Park films are based on Michael Crichton's series of novels about pre-historic beasts being revived by revolutionary gene technology. Frank Marshall and Pat Crowley are co-producing the film alongside Steven Spielberg, who directed the first two installments in the franchise.

The film will hit theaters June 12, 2015.
