‘Fringe’ is back for the new year with a new episode and on a new day, Friday, on Fox at 9pm tonight.

The J.J. Abrams science fiction series returns with the episode “The Firefly”, which finds guest star Christopher Lloyd (‘Back to the Future’, ‘The Addams Family’) as Roscoe Joyce, the keyboardist of Walter’s favorite ’70s band. Together, they uncover some amazing parallels in their lives. Meanwhile, the Observers are back, and one of them wants the Fringe team to reverse a critical error.

About the show:
The FBI teams up with a formerly-institutionalized scientist – who was performing experiments on the fringe of real science – and his son to investigate weird crimes that are seemingly part of a larger pattern, and may be connected with a global company called Massive Dynamics.
