Gary Oldman (The Dark Knight Rises) and Dominic Monaghan (The Lord of the Rings) have been added to the cast of Doug Rath‘s upcoming film Monster Butler. The film chronicles the life of Roy Fontaine (Malcolm McDowell) a con-man who becomes a serial killer as he descends into madness. Oldman will play the character of Wiggy, a taxidermist who helps Fontaine with some of his crimes before Fontaine truly loses it. Monaghan will play David Wright, an important part of Fontaine’s life and the one who truly starts his deep descent into madness. The plot looks really promising and the cast is exceptional, so I expect the film to be one to keep your eyes on.
