According to Deadline, Orange is the New Black actor Michael Chernus has been cast in Spiderman: Homecoming as the villain Phineas Mason, a.k.a. The Tinkerer. In the comics, the Tinkerer is a brilliant inventor with the ability to put together gadgets out of little more than household spare parts. Instead of using those powers for good as say, MacGyver would have, The Tinkerer instead uses them toward more nefarious ends. One of which naturally, is defeating the web-slinger.
