LOS ANGELES — One of the last of Hollywood’s great old-school impresarios, Jerry Weintraub once said he had “the most important phone book in the world.”

“I can get anything done, anywhere, at any time,” the legendary producer told the Los Angeles Times in 2012 in what amounted to a kind of personal motto.

Weintraub was well-known for that kind of braggadocio, but it was hard to argue with him. In a career that spanned half a century, he proved a force in the worlds of music, film and television. He died Monday at 77.

Weintraub had an eye for talent, discovering a singer-songwriter named John Denver, for example, and launching him to international stardom. He was credited with helping revitalize both Elvis’ and Frank Sinatra’s careers.
