just ingenious enough to be plausible and still a lot of fun and this be a pure slice of the 1970s ( even the cop need haircut badly . ) . shot in and around london and the plot of the american ex con who try go straight but find himself send a an electrician to a bank in mayfair and and then have the screw put on by crime lord david niven and and find himself plot the crime of the century be well handle . i like it simplicity and even innocence and it hark back to a time when caper film where just that and a caper and and violence wasn not a part of the deal . all in all you could do a lot bad than watch this represent it have enough twist and turn to give it some oomph and a cast that obviously have fun make it . nicely make and watchable .
