This is old news, but I didn't notice it until this past Monday: The upcoming feature Serenity now has it's trailer online.
The film is a continuation of the ill-fated Fire Fly TV series. I really liked that show as it was an interesting concept, a sci-fi western. I thought it was beautifully written with some excellent humour and dry, sarcastic wit as well as really well developed and simply interesting characters.
I'm looking forward to the film, as it looks like some light will finally be shed on many unanswered questions from the series.
