Fringe‘s move to Fridays, which takes hold on January 21, is looking more and more like a really terrific thing.

Not only has Fox been promoting the heck out of the time-slot change, but Fringe‘s new “under the radar” home apparently has opened the door for even freakier storytelling.

Noting that Fox “has always been pretty cool” about letting Fringe push the envelope, series creator J.J. Abrams tells TVLine that said envelope’s seams have achieved outrageous new levels of elasticity.

“When we made the move and [executive producers] Joe [Chappelle] and Jeff [Pinker] started pitching stuff, we thought, ‘Well, this will probably get a little pushback,'” Abrams shares. “But they [at Fox] were like, ‘OK, sounds good!'”

J.J. didn’t want to spoil what’s to come during the back half of this season by detailing any of the especially “out there” fare. Instead, he vaguely spoke of “visual things” that “if I had done in a film, the PG-13 rating would have been taken from us.”

Fox, however — as touted in the promos — apparently looks forward to its Fridays being freaky. “They have been amazingly and gloriously lenient in what were able to do,” Abrams reports. “It feels like unbridled, unhinged Fringe.”

Fox entertainment chief Kevin Reilly indicated as much speaking to the Television Critics Association winter press tour on Tuesday, saying the Fringe creative team should be feeling “really liberated” in its new time slot. “I think now they can say, ‘You know what? We are playing to our fans — [but are] happy to take anyone new that wants to get on board.”

Are you looking forward to Fringe “unhinged”?
