Bob Givens, the animator best known for his redesign of Bugs Bunny, has died aged 99.

Givens' career spanned over 60 years and he worked as an animator for companies such as Disney, Warner Bros, and Hanna-Barbera.

Givens also drew cartoon characters such as Tom & Jerry, Daffy Duck, Alvin and the Chipmunks and Popeye.

His daughter, Mariana Givens confirmed his death on her Facebook page earlier this month.

Givens' first role, in 1937, was at Disney where he worked on Donald Duck and Snow White cartoons.

He served in the US army during the World War Two, before returning to the animation industry. Givens' career spanned over 60 years.
