Hugh Griffith was a Welsh actor known for his exuberant performances and extraordinary face. He appeared in a number of high prestige blockbuster films in supporting roles, but wasn't fussy, also cropping up in horror films and sex comedies and even co-starring with Cliff Richard in 'Take Me High'. He's seen here as cheeky grave digger / grave robber Mickey in 'Cry Of The Banshee'.
He'll be back, the rascal. Thanks to Andrew Demetrius for the suggestion.
