A new trailer for Patrick Stewart-led series Star Trek: Picard has dropped at Comic-Con, featuring a couple of big surprises for Trek fans.

Star Trek: Picard sees Jean Luc lured out of retirement for a new mission with a new crew and, as the trailer reveals, faces the return of an iconic enemy…

It was also reveals that Next Generation crewmates Jonathan Frakes and Marina Sirtis – as Will Riker and Deanna Troi, respectively – will be back.

Initially reluctant to return to the Star Trek universe, Stewart said it was the subject matter of the proposed new series, as well as the distinguished writing team onboard, that won him over. “I knew that something incredible was going to happen and I wanted to be a part of it.”

Star Trek: Picard will beam down in 2020.
