The location used for the Bergman house is Hall Barn in Beaconsfield, Buckinghamshire. The same location is also used in Season 3, Episode 2 (The Eyes of Tiresias) for the Masson house.
Final on-screen acting role of Jeffrey Segal.
This episode guest stars Bill Bailey. The previous episode guest started Tamsin Greg. Both of these actors appeared together on the hit sitcom 'Black Books.'
Hall Barn (the house used for the Bergman's property in Jonathan Creek) is the same house that was used in the Midsomer Murders mystery "Murder on St Malley's Day" in 2002, and both feature the actress Victoria Shalet.
