"Penthouse" is a first-rate example of "they don't make 'em like that anymore." The tale of a society lawyer turned criminal defense attorney -- out to prove the innocence of the accused murderer who waltzed off with his fiancée -- zips along. The dialog of the fabled Hackett-Goodrich team is sassy and clever. The relationship between lawyer Warner Baxter and Nat Pendleton as the racketeer who's his guardian angel perks up the plot. But it's Myrna Loy as the call girl who joins forces with Baxter to nail the real killer who shines. There are certain people the camera finds irresistible. And here, as the most lovable fallen woman of the pre-code era, Loy demonstrates the impish allure that would light up the screen for years to come.
