Float Out was written by none other than Patton Oswalt, the stand up comedian, best known for his role as the nerdy Spence Olchin in the long lasting sitcom The King Of Queens. Apparently Oswaft is a serious Browncoat (fan of Firefly/Serenity)!
What's even more interesting is the fact that the write up for Float Out mentions two things of note.
(1) That a surprise cameo in the comic will "...leave Serenity fans reeling...".
And (2) It has a reference to Serenity's future?!? What is THAT supposed to mean? Are there any plans for Firefly/Serenity to continue in any way shape or form in the near future? Joss Whedon, the creator of the franchise, did recently have his latest show Dollhouse cancelled, so it is a possibility. But I don't want to get my geeky hopes up... Even though I'm going to. :P
For those of you who have no idea what I've been talking about or what Firefly/Serenity is, visit http://www.serenitymovie.com/. I highly recommend it. Just be sure to watch the show first!
