'Will William Shatner appear in Star Trek 3?' has been the question on every Trekkie's lips.

But after being told not to speak about the film for a second time, the original Captain T. Kirk says he's in quite the 'dilemma' but is 'very excited' about the new film.

'Here's my dilemma, I was cautioned not to speak about this and the next day it was out all over Twitter,' William, 83, exclusively told MailOnline.

Biting his tongue: WIlliam Shatner told not to talk about Star Trek 3 again but says he is 'very excited' for it

'So I talked about it and then I get another phone call telling me to keep quiet again! All I can say is that I'm very excited about the film.'

Last week, Shatner took to social media to shut down reports he was set to star in the third Star Trek film from JJ Abrams.

But the 83-year-old gave fans a glimmer of hope at the Wizard World Nashville Comic-Con on Friday, admitting Abrams had been in touch with him and he would indeed be keen to star in the next film, on the proviso the script had substance.

On the phone: JJ Abrams or one of the producers has been in touch with William to caution him for a second time about talking about the film which could see him return as Captain T. Kirk

William certainly shares a likeness to Chris Pine, the actor who has taken up the Captain Kirk mantle, and is happy when people describe Chris as good looking.

'You know everyone commented on how good looking he is, so by extension that means I am too,' the Canadian actor laughed.

William is heading to London this week to chair The Next Generation panel at Destination Star Trek, and he's certainly a popular face at these sci-fi conventions with thousands of Trekkies expected to attend.

'I love contacting the fans and hearing what they have to say and have them hear what I have to say,' Shatner said.

'I have a good time and there's a certain amount of renewal that I need and it's great to see children and their mothers and their mothers' mothers coming down.'

His turn as the captain of the original USS Enterprise from 1966 to 1969, as well as seven Star Trek feature films, has seen Shatner become a cult icon across the world, though if he was ever offered any other famous roles from the sci-fi series he says he would 'have turned them all down.'

It's certainly hard to see the actor as anything over than Captain Kirk though he's as famous for boldly going where no man has gone before as he is for his covers of pop songs.

Icon: The Canadian actor played Captain T. Kirk from 1966 to 1969 in the original TV series as well as seven feature films

He famously did a spoken-word version of Pulp's Common People, ('though I've never met Jarvis [Cocker]') and was recently 'thrilled' to join Paul Simon onstage to perform Like A Bridge Over Troubled Waters and Paul McCartney during Lucy In The Sky With Diamonds.

At 83 it's amazing the energy William has, and when asked what his secret to staying fit is, he tells MailOnline 'chasing horses in lieu of women.'

His horse riding skill is no secret as the actor rode one of his own mares, named Great Belles of Fire, in Star Trek Generations. In his spare time William also breeds American Saddlebreds and 'competes frequently at fairs'.

Happy with the comparison: William likes that Chris Pine is considered handsome as he says it makes him handsome 'by extension'

Though he won't have time to do any riding when he's in London, the actor still hopes to have a quintessentially British trip.

'What I want to do is do everything typically English,' William said. 'Bring the warm beer to drink and the bland food to eat!'

Destination Star Trek London (DST3), returns to London for three days from Friday 3rd - Sunday 5th October 2014, at London’s ExCeL Centre.
