I, MONSTER (1971) Amicus, fellow Brit studio Hammers biggest rival during the 60s and 70s, produced a number of successful horror vehicles for Lee and his popular co-star Peter Cushing. In this feature, the oft-told tale of Jekyll and Hyde is adapted to showcase Lees abilities to successfully display his duality as an actor. He gives a suitably excitable performance as the obsessive scientist, Marlowe, contrasting brilliantly with his monstrous performance as the psychopathic Blake. Similarly, Lees performance as the ambitious and recalcitrant Marlowe contrasts well with Cushings more cautious and incredulous scientist. Very much a successful role for Lee because of this pairing, its not his best but its an interesting watch nonetheless.
