The official Firefly movie, Serenity, will be in theaters September 30th. Firefly is an old favorite of mine, and I am excited to see that the first Serenity trailer is available. Serenity appears to be a replacement for the continuity established by the original television series. The synopsis for Serenity starts at the beginning of the Firefly series and then runs completely off of the map from there. If you’re interested in the original series, you can purchase Firefly – The Complete Series on DVD.
