Hot Millions is a gentle and amusing comedy, probably too gentle for those who prefer boisterous laughs and breathless pacing. However, those who prefer comedies that sneak up on them and cause them to chuckle appreciatively, Hot Millions will be just their cup of tea. Peter Ustinov and Ira Wallach's screenplay is very well constructed, based upon a simple premise that provides the very workable framework upon which the film is based, and it is filled with small details and little moments that stay with the viewer after the film is over. Eric Till's direction is smooth and assured, and he's quite good at kicking the pace into medium-high gear without letting it spill over into frenetic. Stars Ustinov and Maggie Smith could not be better, nor (and this is the important part) more charming and endearing. They have a quirky chemistry that is immensely appealing, and their considerable comedic skills mesh together seamlessly. Bob Newhart utilizes his deadpan style of humor to good effect, and Karl Malden seems to be having a grand time as the sleazy and not too quick corporate man. Smith would follow Millions with her Oscar-winning turn in The Prime of Miss Jean Brodie.
