The Great Bank Robbery is a 1969 Western comedy film from Warner Bros. directed by Hy Averback and written by William Peter Blatty, based on the novel by Frank O'Rourke.
He and his associates, including partner Lyda Kebanov, plan to tunnel into the vault and blow it up with TNT, just as a Fourth of July celebration drowns out the noise.
The reverend's band is successful, distracting the bank's guards by having Lyda pretend to be Lady Godiva, riding nude on a white horse, with just small flower pasties covering her nipples and groin.
Lyda volunteers to abandon ship, in part because she has fallen for Quick, who finds the proof he needs to convict Kincaid while the reverend and the gold fly safely away.
Vincent Canby of The New York Times had nothing but disdain for the picture: "The Great Bank Robbery, the Western farce that opened yesterday at neighborhood theaters, is probably the least interesting movie of 1969 through this date.
