Jonathan Frakes confirmed this weekend that he and Marina Sirtis will be performing as Riker and Troi in the finale of Star Trek: Enterprise.
During an appearance at the Eleventh Annual SF Ball in Bournemouth, UK, Frakes told the crowd that he and "his Imzadi Marina Sirtis" would both be in the final episode of Enterprise, according to fan reports sent in to the Trek Nation.
Reports had surfaced late last month that the two Star Trek: The Next Generation stars would appear in the Enterprise fourth season finale after a post by an administrator on Sirtis' web site (story). A source confirmed that negotiations were underway, though Sirtis denied the rumours at a convention in Florida (story).
In a recent chat at StarTrek.com, executive producer Manny Coto declined to speak about the finale, saying, "Rick Berman and Brannon Braga are writing it and if they want to spoil it I'd rather have them spoil it themselves! But I will say that it does not involve time travel. That's as much as I will say. And, it's a very cool story."
Frakes and Sirtis were last seen as Riker and Troi in Star Trek Nemesis, when the two left Captain Picard's Enterprise so that Riker could take command of the USS Titan.
The Enterprise series finale is scheduled to air on May 13th. Thanks to Mark Newbold and Dax X for their reports on the SF Ball.
