It’s likely the best role I’ve seen for Eddie Murphy in a while; he brings a youthful energy and sharp wit to the part. He plays “Axel Foley,” a police officer from Detroit who gets caught up in some illegal activities happening in Beverly Hills, a wealthy and very proper Los Angeles suburb. Despite the serious objections of "Lt. Bogomil" (Ronny Cox), he ends up partnering with two detectives, "Taggart" (John Ashton) and "Rosewood" (Judge Reinhold), as they investigate the murder of a friend from Detroit. This quickly leads them into a profitable – and dangerous – drug operation. The humor comes from the contrast between Murphy's character’s personality and the refined environment he finds himself in, giving him ample opportunity to shine. The script delivers rapid-fire jokes, and the other actors play well off of him, often becoming the target of his humor. As the relationships progress along familiar lines, the film successfully blends comedy, physical gags, and some action sequences with just enough class to avoid being embarrassing. There’s no question that the police will catch their suspect – portrayed by a rather over-the-top Steven Berkoff – but the journey is amusing and enjoyable. Stephen Elliott deserves attention as "Chief Hubbard," whose skepticism about what's happening right under his nose is genuinely funny, as is Bronson Pinchot's character, "Serge." The film also features a pretty memorable soundtrack—even though I didn’t care for “Axel F”—and it’s generally good entertainment.
