After a bright start, this slick MGM amnesia comedy loses some momentum. But William Powell is constantly funny, doing a lot more physical comedy than you might be accustomed to seeing from him - and doing it very well. Myrna Loy looks gorgeous in a variety of fabulous costumes, but is mostly relegated to the "straight woman" role; Frank McHugh is Powell's real comic partner in this one. **1/2 out of 4.
