The critic Irving Wardle called Pinter's early plays "comedies of menace". He meant that the plays begin with an apparently innocent situation. The situation becomes both threatening and "absurd" as Pinter's characters behave in strange ways. Pinter acknowledged that Samuel Beckett influenced his early work. They became friends, sending each other drafts of their works in progress for comments.
Pinter was married to Vivien Merchant from 1956 until they divorced in 1980. He was married to Antonia Fraser from 1980 until his death. He was diagnosed with oesophageal cancer in 2001 and died from the disease in London seven years later when it metastasised to his liver.
