Michael Byrne

Michael Byrne: 

Gimlet-eyed, steely establishment type with a hint of menace, he has had a few high profile film roles and a very solid TV drama career, moving easily between playing Whitehall mandarins and Nazi psychopaths, although perhaps that's not such a huge leap. Movie highlights are 'Indiana Jones & The Last Crusade' (1989), 'The Eagle Has Landed' (1976), 'Gangs Of New York' (2002), 'Braveheart' (1995) and 'Butley' (1974). On television, he was seen in 'Within These Walls', 'The Gentle Touch', 'Hamish Macbeth', 'Smiley's People' and more recently 'Coronation Street'.

Richard O'Callaghan

Richard O'Callaghan: 

Son of the inimitable Patricia Hayes, he is probably best known as the shy tinfoil aeroplane enthusiast Bertram Muffet from 'Carry On Loving' and the idealistic young master Boggs from 'Carry On At Your Convenience'. 

He has aged into a rather craggy and disreputable-looking type, with some Shakespearean stage roles to back up his parts in TV from 'Dalziel & Pascoe', 'Mr Pye', and 'McCallum', to 'Boon', 'Casualty', and 'Heartbeat'-type fare. I should also mention his role in the bleak, bisexual, black-comedy, 'Butley' (1974), with Alan Bates. Directed by Harold Pinter.
