In the 2002 theatrical release Borstal Boy, based very loosely on the life of Irish poet-activist Brendan Behan, Ingleby played a bully in an English boarding school for juvenile offenders.
Ingleby has also made one-off appearances in television programmes such as Hustle, Clocking Off, No Angels, Fat Friends, Jonathan Creek, Spaced, Dalziel and Pascoe, Cadfael (Pilgrim of Hate) and The Bill.
[5] Ingleby headed the cast of the 2008 three-part television crime drama A Place of Execution as DI George Bennett as he was in the 1960s determined to close the case of a missing girl.
When not working in films and television, Ingleby remains active on the stage, where his credits include Puck in Midsummer Night's Dream, Alexander in Nicholas Wright's Cressida and Katurian in Martin McDonagh's The Pillowman.
In the same year, two more feature length audio stories (Warriors' Harvest and King's Command) have been produced by Spiteful Puppet with Ingleby once again playing the role of "De Nicholay".
[citation needed] That same year he provided spoken word narration on the progressive rock album Please Come Home which the British musician John Mitchell released under the project name Lonely Robot.
