The Scarlet Clue* has a lone blooper . . . that I know of anyway!
Birmingham Brown's screams don't match the way his mouth movies when he's caught in the Hamilton Lab between the lightning "lamps."
. . .
How about a bonus question?
What does The Scarlet Clue have in common with Charlie Chan in Panama?
(Not the best picture of Virginia Brissac but she was frequently made-up as to be difficult to recognize as in "The Ghost Breakers" and "Saratoga Trunk.")
Their bad guys were bad girls!!
In Panama, it was Mary Nash!
