After the trailer of "Star Trek Beyond" was recently leaked, Paramount released it officially before the scheduled date.

Joining the cast of the first two instalments of "Star Trek" reboot are Idris Elba and Sofia Boutella. However, Paramount hasn't revealed what characters they will be playing in the movie.

Speculations are rife regarding the role of "Thor" actor Idris Elba and what character he will be playing in the movie.

In the trailer, Elba is nowhere to be seen. Instead, we see a monster-like alien creature who highly resembles Commander Kruge from the original "Star Trek" television series.

As there is no official confirmation of Elba's character, given his personality and previous roles, he will be apt to play Kruge in the movie.

In the original series, Kruge killed Kirk's son and hence, it established him as one of the most ruthless and brutal villains in the Star Trek universe.

However, Kirk doesn't have a son in the reboot, hence, if Kruge is going to appear, it must be something through a completely different cause.

Nevertheless, Kirk hijacked the Federation tech designed to terraform a planet and repurposed it to destroy multiple worlds. If the upcoming movie follows this storyline, then there is no argument that Elba will be a pretty cool villain in the movie.

Besides, Kruge and Kirk had an epic fight scene in the television series that can make up a pretty good climax for the movie.

All speculations aside, the fans will have to wait until the next trailer is released to know whether Elba will be playing Kruge or not.

"Star Trek Beyond" is a sequel to 2013's science fiction film "Star Trek Into the Darkness" and is the third movie in the reboot series. The film is directed by Justin Lee (The Fast and the Furious 3-6) and is produced by JJ Abrams, who had directed the first two movies of the series.

Chris Pine and Zachary Quinto reprise their roles as Captain James T Kirk and Commander Spock, with Simon Pegg, Karl Urban, Zoe Saldana, John Cho and Anton Yelchin reprising their roles from the previous film.
