Continuity mistake: During the robbery, the taxi driven by Danny Green changes from an Austin to a Morris Oxford and back again. Both types are the same colour, but the Austin is the one with the rounded radiator grille, and the Oxford has a flat radiator.
The Ladykillers (1955)
Ending / spoiler
Directed by: Alexander Mackendrick
Starring: Herbert Lom, Peter Sellers, Alec Guinness, Cecil Parker
Tom Hanks and his crew successfully rob the casino but everyone dies in their own dark and ironic way (Tom Hanks too). The old lady keeps $1.6 mil but decides to donate it to a bible school (not knowing it preaches racism), again, a dark and ironic end.
