About this converter
Firefly ran 14 episodes in one Fox season, and the runtimes show a network hour with almost no fat. The two-hour Serenity pilot runs 86 minutes of content once ads are removed. Every other episode runs 42 to 44 minutes. The Train Job at 42 is the shortest because it was cut fast as a replacement opener. Safe, Ariel and War Stories run 43. The rest run 44, including Out of Gas, Jaynestown and Objects in Space. Three episodes never aired on Fox in 2002 and debuted later on cable, but their masters match the same 44 minute line. Total content for the series is about 630 minutes.
How to use it
Pick two episodes and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first episode, one holds the matching count of the second, one holds the time in minutes. Try 1 Serenity pilot against Train Jobs to see the double against the rush pilot.
Runtimes are DVD and streaming content figures without ads, cross-checked between Fox masters and IMDb episode pages. Broadcast slots were one hour, or two hours for the pilot. The Serenity feature film at 119 minutes is not mixed into this episode table.
