Box office The film earned $524,000 in the US and Canada and $314,000 elsewhere, against production costs of $892,000, incurring a loss.
Variety magazine's review at the time was more positive. The staff wrote, "Arch Oboler, radio’s master of suspense, has effectively transposed his technique into the visual medium with
The Arnelo Affair. Strictly speaking this is not a whodunit, nor can it be catalogued as a psychological suspense picture ... There’s never a question as to who committed the murder, but the crime is secondary to its effect on the characters involved. Until the film’s very climax, no hint is given to the ultimate denouement. Dialogue instills the feeling of action where none exists for much of the footage, and the gab is excellent but for a couple of spots when Oboler gives vent to florid passages." ==References==
