Christopher Evan Welch, who appeared onstage in numerous plays, in films including Steven Spielberg’s “War of the Worlds” and “Lincoln,” Paul Thomas Anderson’s “The Master” and Woody Allen’s “Vicky Cristina Barcelona,” as well as on television, died early Monday at a Los Angeles hospital, his agency Paradigm confirmed. He is believed to have been 48. (there's nothing about the cause, so I guess they don't know yet?)
The actor had been in L.A. shooting a role in the upcoming HBO series “Silicon Valley.” Welch made his Broadway debut in 1997 in the play “London Assurance.” He played the Reverend Samuel Parris in the 2002 revival of Arthur Miller’s “The Crucible” on the Rialto and had a role in “Festen” in 2006. He also had numerous off-Broadway credits.
As a New Yorker and a diehard "Rubicon" fan I'm especially sad to hear this. 48 is way too young. (And yes, he was on SVU a few times, notably in that "911" ep.)
