Zachary Quinto Mourns Loss of Signature Theater's James Houghton

Zachary Quinto steps out to walk his dogs on Friday (August 5) in New York City.

The 39-year-old actor took to social media earlier in the week to mourn the death of New York City’s Signature Theater founder James Houghton.

“Jim houghton. a brother in arms to artists of all kinds. a man of dignity and grace whose tireless commitment to creativity and creators was inspiring beyond words. i am honored to have worked with him and deeply saddened by his untimely passing. it seems so unfair to have to say goodbye to yet another beautiful soul. he fought valiantly and with authentic joy for life. now in death may he find true peace. i am holding his wife and children in my heart and sending them prayers of comfort. sleep easy brother. you have earned this rest,” Zachary wrote on Instagram.
