The Stars aligned: Mark Hamill and George Takei join forces as Star Trek and Star Wars legends guest star in The Neighbors

Self confessed science-fiction geeks will be jumping for joy as two of their biggest icons have combined forces.

The worlds of Star Trek and Star Wars have crossed over thanks to a modern day sci-fi comedy television show.

George Takei and Mark Hamill have guest starred on ABC comedy The Neighbors, but have not reprised their famous roles.

Crossing over: Science fiction legends George Takei and Mark Hamill have guest starred in The Neighbors

Takei, who played Hikaru Sulu, helmsman of the USS Enterprise in the television series Star Trek, teamed up with Hamill, who played Luke Skywalker in the original three Star Wars films.

The space journeying legends travel from a galaxy far, far away to the final frontier - or in this case the season one finale.

Takei appeared as Larry Bird's (Simon Templeman) father who comes to Earth with an important announcement, and Hamill takes on the role of a co-worker.

The Neighbors is an offbeat comedy that deals with a normal family that moves is living in a community of extraterrestrials.

Despite George and Mark appearing at several of the same science book conventions the pair had never before met.

Hamill told TV Guide: 'I apologized to George for not knowing Star Trek as well as most of the people who come up to him, and he thought that was a breath of fresh air.'

A return to the big screen could be imminent for Mark as he recently revealed that he and his co-stars from the iconic trilogy are in talks to reprise their famous roles.

The original crew: The 61-year-old wants to ensure Carrie, who plays Princess Leia and Harrison, Han Solo, are also onboard, asking, 'Are we going to have the whole gang back?'

He let it slip that original director George Lucas reached out to him.

And he revealed that Harrison Ford and Carrie Fisher are also now in talks to appear in the latest installment of the franchise Star Wars VII, or even spin-off films.

He told Entertainment Tonight: 'They're talking to us.'

'George [Lucas] wanted to know whether we'd be interested. He did say that if we didn't want to do it, they wouldn't cast another actor in our parts - they would write us out.'

Retro feel: The star said he hoped the film is more like the original and does not use too much CGI

He added: 'I can tell you right away that we haven't signed any contracts.

'We're in the stage where they want us to go in and meet with Michael Arndt, who is the writer, and Kathleen Kennedy, who is going to run Lucasfilm.

'Both have had meetings set that were postponed - on their end, not mine. They're more busy than I am.'
