US comedian and actor Bob Newhart has died at the age of 94.
Known for his roles in the Christmas film Elf and US sitcom The Big Bang Theory, Newhart also had his own programme The Bob Newhart Show.
Jerry Digney, Newhart's publicist, said Newhart died at the age of 94 after "a series of short illnesses".
Bob Newhart launched his career as a standup comic in the late 1950s.
He gained nationwide fame in the US when his routine was captured on vinyl in 1960 as 'The Button-Down Mind of Bob Newhart', which went on to win a Grammy Award as Album of the Year.
Over the years, Bob Newhart also appeared in several movies, usually in comedic roles.
Among them: Catch 22, In And Out, Legally Blonde 2 and Elf, as the diminutive dad of adopted full-size son Will Ferrell.

Newhart continued appearing on television occasionally after his fourth sitcom ended and vowed in 2003 that he would work as long as he could.
"It's been so much, 43 years of my life; [to quit] would be like something was missing," he said.
Though nominated several times, he never won an Emmy for his sitcom work about which he quipped: "I guess they think I'm not acting. That it's just Bob being Bob".
