Refresh for updates… Bob Einstein is being remembered by castmates, colleagues and his brother Albert Brooks as a comedian’s comedian — “excruciatingly brilliant,” as his friend and Curb Your Enthusiasm co-star Richard Lewis described him.

Series creator and star Larry David said in a statement: “Never have I seen an actor enjoy a role the way Bob did playing ‘Marty Funkhouser’ on Curb. It was an amazing, unforgettable experience knowing and working with him. There was no one like him, as he told us again and again. We’re all in a state of shock.”

Lewis and David were joined by Curb castmate Cheryl Hines and writer David Mandel in praising the “Super Dave” creator. “We lost a friend today,” tweeted Hines, “Thanks for all of the laughs on Curb Your Enthusiasm…The comedy world will miss you.”

Einstein’s longtime pal Lewis tweeted: “His long career is hard to match. His role on #curbyourenthusiasm was excruciatingly brilliant! Our cast and crew will be devastated.”

Wrote Brooks: “R.I.P. My dear brother Bob Einstein. A great brother, father and husband. A brilliantly funny man. You will be missed forever.”
