William Shatner says he would star in Quentin Tarantino's "Star Trek" movie if the script was to his liking

William Shatner as Captain Kirk in Star Trek

It had been  revealed that Quentin Tarantino pitched a Star Trek film to JJ Abrams and Paramount, and that we should take the news very seriously. Tarantino had met for hours with writers Mark L. Smith, Lindsey Beer, and Drew Pearce. The goal was to  kick around ideas for this to possibly happen. Rumors indicate that Smith, who wrote The Revenant, seems to be the man for the job. Tarantino has stipulated the film will require to be R rated, and Paramount and Abrams are okay with that. There has NEVER been a "Star Trek," or "Star Wars" movie for that matter, that hasn't been rated PG-13.  Of course, we know that an R-rated movie is not Box-Office kiss of death anymore, as Fox's Deadpool justifiably reminded us that a few years ago. 
Now comes the news that William Shatner, Captain James T. Kirk, would love to star in the movie, provided the screenplay is to his liking. Shatner responded to somebody on Twitter when asked:

Depends on the script but if it was good then absolutely. Why not? https://t.co/qaf9Bolg21

Shatner was not asked to appear in J.J. Abrams' 2009 and 2013 Star Trek reboots and the rumor seemed to indicate he wasn't too happy about that. So this would be a much appreciated welcome back for Captain Kirk.
