It’s a longstanding tradition for actors at a certain point in their career to lend their voices to an animated favourite, and this is a particularly fun one.

Ian McKellen, veteran star of stage and screen, will lend his voice to the character of Dr Pritchfield – a child psychologist enlisted to help Stewie after he acts up at school – on Family Guy’s fifteenth season.

This is notable for British audiences because the episode will be penned by Vicious writer Gary Janetti. Keep an eye out for the episode when it airs later this year.
