Amazon rode to the rescue of Ripper Street in early 2014, shortly after the BBC had decided not to move beyond Season 2. Season 3 of the period drama launched on the UK’s Amazon Prime Instant Video in November last year and was streamed more than any other TV show, attracting larger viewing audiences than some major U.S. series. Amazon has now committed to two further seasons for Prime Instant in the UK. Filming is to begin immediately with launch dates still to be set.

Matthew Macfadyen stars in the Victorian-era detective drama that’s set in the aftermath of the Jack The Ripper murders. Ripper Street is produced by Tiger Aspect and Lookout Point and created by Richard Warlow.

Exec producer Saul Venit of Lookout Point, says, “Keeping this series going for 37 episodes over five series is a hugely exciting achievement and is testament to the extraordinary creative results, as well as to the visionary teams at BBC Worldwide and Amazon as our core commercial partners.”

Amazon is making the move as a further significant investment in original and exclusive TV on the heels of its Golden Globe wins for Transparent.
