Priredba knjige Rogerja Lewisa o igralcu, ki se ga najbolj spomnimo kot inšpektorja Clouseauja v filmih o Rožnatem panterju. Film skuša pokukati za mnoge obraze Petra Sellersa, da bi odkril, kako je ta komični genij pristal na robu norosti.Življenje in smrt Petra Sellersa spremlja burni vzpon priljubljenega britanskega komika in radijskega igralca na BBC-ju do enega najbolj nadarjenih svetovnih komičnih igralcev. Sellers, čigar mati je bila izjemno ambiciozna in posesivna, se je boril, da bi uredil svoje odnose z ženskami, slavo in s svojimi mnogimi osebnostmi. Kljub svojim zakonom, priznanju kritikov in poklicnemu uspehu pa ni imel samozavesti. Življenje in smrt Petra Sellersa razkriva zasebno trpljenje tega nadarjenega in karizmatičnega igralca, ki ga je gnalo do izjave: "Sovražim vse, kar počnem," kljub temu pa nas spomni, zakaj je bil svet navdušen nad tem komičnim genijem, ki je postal mednarodna kulturna ikona.
The professional and personal life of actor and comedian Peter Sellers was a turbulent one. His early movie fame was based primarily on his comic characterizations, often of bumbling and foreign-accented persons, characters which he embodied. As his movie fame rose, he began to lose his own personal identity to his movie characters, leading to self-doubt of himself as a person and a constant need for reassurance and acceptance of his work. This self-doubt manifested itself in fits of anger and what was deemed as arrogance by many. In turn, his personal relationships began to deteriorate as his characterizations were continually used to mask his problems. His first wife, Anne Howe, left/divorced him and his relationships with his parents and children became increasingly distant. His relationship with his second wife, Swedish actress Britt Ekland, was based on this mask. In his later life, he tried to rediscover himself and his career with what would become his penultimate film role, that of Chance in Being There (1979).
