Diamonds For Breakfast (1968)

A Russian playboy (Marcello Mastroianni), a descendent of the Romanov dynasty that was overthrown in the 1917 Russian Revolution, concocts a daring plot to steal the Romanov crown jewels from a London museum. To help him carry out the plan, he gathers together a crew of beautiful women. Directed by Christopher Morahan. Is there anything worse than a comedy that just is not funny? DIAMONDS wants to be a swinging 60s British comedy heist movie but the laughs aren't there (though you can see where they're supposed to be) and as a heist movie, it's a bust. I realize we're not supposed to take it that seriously but when you have security men protecting the Russian crown jewels in a museum and they ignore their jobs and the cameras focused on the exhibition whenever a sexy girl walks in, gimme a break! Does no one get suspicious? Mastroianni is one of cinema's greatest actors but not in his few English language films. Even in 1968, they must have known something was wrong as the movie was never released in the U.S.  With Rita Tushingham, Margaret Blye, Francesca Tu, Leonard Rossiter and Bryan Pringle.
