Whipsaw ★★★½

Spencer Tracy had switched studios from Fox to MGM in 1935, and this role has more in common with his tough guy programmers than the more sophisticated fare his new studio would eventually offer him.

This is a fairly minor crime picture but it's lifted by the sparkling chemistry between Tracy (as a G-man posing as a crook) and Myrna Lou (as a hard-boiled jewel thief). They positively crackle in their scenes together, which makes this film a pleasure to watch.

Director Sam Wood is content to let his stars just do their thing, and they do it well. Romance beckons by the halfway point, and the whole story of the stolen pearls sinks into second place.

A happy discovery, currently available on YouTube.
