No, that’s not official but brilliant youtuber jaronpitts stitched together a fan-made trailer that imagines Fillion as such. The trailer is INCREDIBLY crafted, even by studio standards, with what appears to be random footage from Nathan’s career (which I might add I am a huge fan of). I would not be the least bit surprised if this gets BOTH of them the job.
Let’s make this happen through the AWESOME POWER OF THE INTERWEBS! Pass it on!!!
