The Unknown Purple
Inventor Peter Marchmont has discovered a purple light that renders the user invisible. On his release from prison, Marchmont, disguised as Victor Cromport, uses the light to revenge himself against his former wife, Jewel, and her partner, James Dawson, who framed him for theft. Making himself invisible, Marchmont gradually ruins Dawson. He so wins Jewel's confidence and love that she is willing to kill Dawson at Marchmont's request. Finally, Marchmont leaves the scheming couple to their own misery and marries Jewel's sister, Ruth Marsh.

🎬 MovieFinder's Take
The Unknown Purple is an acquired taste at 0.0/10. We recommend checking the trailer and synopsis before diving in.
Not every film is made for everyone. Read the synopsis, watch the trailer — you'll know right away if it's for you.
A classic from 1923. They don't make them like this anymore — which is exactly why you should watch it. Best for: genre fans and those open to something unconventional.
