Steel Against the Sky is an engaging yet uneven blend of comedy, romance and melodrama set in the construction industry. Another example of the kind of quick and snazzy movies that Warner Brothers ground out like sausages in the early '40s, but it's scripted and directed so indifferently that the whole project cries out for the macho verve of a Raoul Walsh. Lloyd Nolan and Craig Stevens star as bickering brothers vying for the attentions of pretty Alexis Smith. What ensues is very predictable, but Stevens and Smith have undeniable chemistry (the couple latter married and stayed united until Smith's death in the 1990s) and the thrills come assuredly in the climax atop a huge, slippery bridge. For comedic relief, Walter Catlett annoys as a bumbling scientist. Luckily, his scenes aren't too long. A young and unknown Jackie Gleason has a funny little scene early on.
