I just read elsewhere on this site that Peter Serafinowicz is writing a Brian Butterfield film with him as a detective.
First an Alan Partridge film, now a Brian Butterfield film. This is excellent news!
Brian Butterfield The Movie?
It's being co-written with Andrew Ellard, who discusses it during our podcast: https://www.comedy.co.uk/podcasts/british_comedy_podcast/11_andrew_ellard/
