London After Midnight earned $721,000 in
theater rentals from the United States and Canada and an additional $283,000 from foreign rentals, giving the studio a profit of $540,000. A positive review ran in
The Film Daily, calling it "a story certain to disturb the nervous system of the more sensitive picture patrons. Thrills and weird doings in profusion. Probably a trifle too spooky for the timid soul. If they don't get the creeps from flashes of grimy bats swooping around, cobweb-bedecked mystery chambers and the grotesque inhabitants of the haunted house, then they've passed the third degree." Marc Bowman of
The Oregonian praised the film as "as nerve-wringing a piece of screen fiction as has been seen in these parts for many moons," noting Chaney's makeup as "bizarre" and "striking."
The Warren Tribune noted that Lon Chaney is "present in nearly every scene, in a dual role that tests his skill to no small degree." The review highlighted that this subdues Chaney's prominence and allows the plot to be better communicated, but it also causes the film to "not rank among his best productions." A review by
The Brooklyn Daily Eagle noted: "It is pleasant to report also that there is none of the usual stupid comedy relief in
London After Midnight to mar its sinister and creepy scheme. That ought to make it the outstanding mystery film of the year."
Motion Picture Magazine wrote, "Lon Chaney is back in a get-up which would make any sensitive girl quiver and quake on a dark night, but which doesn't require any contortions or self-torture. This is a dark, foul mystery play, which has certain elements as horrid as anyone could ask... you sit through it in a sort of daze."
Photoplay enthused, "The disguise that [Chaney] uses while ferreting out the murderer is as gruesome as any he has ever worn... The suspense is marvelously sustained. Chaney plays a dual role, and when conventionally clad, is a little less convincing than usual. In the other role, perfect!" ==Preservation==
