If you’re still spinning over the casting news that David Tennant will no longer star in the upcoming dark comedy Burke & Hare, there’s more where that came from. No one will be replaced, but several other well known actors have signed on to the film. According to THR, Simon Pegg and Andy Serkis will be joined by Tom Wilkinson and Isla Fisher in the John Landis production.

Burke & Hare centers on a pair of Irish immigrant murderers in early 19th century Edinburgh who sell the corpses of their victims to the local medical college. The film is based on a true story about the U.K.’s earliest serial killers, whose names were William Burke and William Hare. With names like that, it sounds like they were destined to be partners in crime.

Fisher joins the cast as a young actress and Pegg’s girlfriend who’s looking for a patron, she also may or may not be an accomplice to the duo’s heinous murders. Wilkinson will star as “Dr. Robert Knox, an anatomy lecturer looking for fresh corpses.” He sounds like a regular customer or perhaps someone who could be used to catch the killers in the act.

Burke & Hare also features Dan Aykroyd and Bill Nighy, and will begin production on January 31 in Edinburgh and London. This will be the first feature that Landis has directed in years, so it will be interesting to see if he still has what it takes to pull off a horror comedy.
