On Regardless Trivia
- Charles Hawtrey had the start of a long run disagreement
with Peter Rogers while filming Regardless, concerning his billing, stating
that "He was a comedian", but Rogers was having none of it, and in
fact Hawtrey had less to do in this film than he might.
- Terence Longden's role was destined for Leslie
Phillips, but he bailed out before the start of filming, expressing concerns
over typecasting, so Hudis re-shaped and reduced the role.
- Whilst filming the scene at a wine tasting party,
Gerald Thomas switched the non alcoholic drink in Joan Sims' glass for real
Gin, look at her face for the first mouthful.
