Withnail & I Photos and Images
Illustrator Ralph Steadman was the man behind much of the imagery we associate with Withnail and I. This includes the unforgettable illustration that accompanied the film's release and was used on many publicity posters.
There also exists a series of 'behind-the-scene' photos that shipped as extras on the Region 2 DVD.
