 Olivier spent the last fifteen years of his life in securing his finances and dealing with worsening health , which included thrombosis and dermatomyositis , a degenerative muscle disorder . Professionally , and to secure financial security , he made a series of advertisements for Polaroid cameras in 1972 , although he stipulated that they must never be shown in Britain ; he also took a number of cameo film roles , which were in " often undistinguished films " , according to Billington . Olivier 's move from leading parts to supporting and cameo roles came about because his poor health meant he could not get the necessary long insurance for larger parts , with only short engagements in films available .
