elaborate caper movie which and while nothing special and be redeem by it unusual israeli setting . robert shaw have a dual role a an industrialist and his security device maker twin ( the karate match between the two shaw constitutes perhaps the film low point . ) . ex con and thief richard roundtree ( often clothe in conspicuously outlandish costume ) and lover barbara hershey ( bill barbara seagull ) be industrialist shaw unwilling accomplice in a diamond robbery whose security system be devise by none other than his brother ( whom he admit to not like . ) . shelley winter turn up in irrelevant bit a an annoying american tourist while get carter ( 1971 ) roy budd provide the score . caper movie be among my favorite ( maybe and it because i work in a bank ) but this be a very mild addition to that excite thriller subgenre chiefly because of an unconvincing plot also involve child kidnapping and a counter robbery from a church to mislead the israeli police and the gang don a series of silly disguise and and ultimately and a burglary which remain unfulfilled ( again and a fashionable twist in the cynical 1970s but rather ludicrous in this context . ) .
