While Richard Arlen's early film career was amazingly successful and he was featured in the first Oscar winner, "Wings" (1927), despite his good looks the roles he was given in movies declined over the years until he was consigned to playing only in B-movies in the 1930s and 40s. Most of these are modestly enjoyable but slight films made for third-rate studios like PRC...and "Accomplice" is certainly a prime example of the sort of subpar Bs he made during this era.
In this movie, Arlen plays a private detective who makes the mistake of taking a case from his old girlfriend...a woman who ended up leaving him for another man. Soon, he's embroiled in a weird case where things just didn't seem to make sense until late in the movie. It went from Arlen being hired to find a missing husband who experiences bouts of amnesia to a case involving murder!
The film has some action and the plot is a tad confusing and muddled. None of it is bad....though none of it is particularly good either. An okay time passer and nothing more.
