One of his most successful books, "The Collected Bulletins of Idi Amin" (a collection of his "Punch" articles about Amin) was rejected for publication in the United States on the grounds of racial sensitivity. These Bulletins were later made into a comedy album, "The Collected Broadcasts of Idi Amin" with the actor John Bird. After the Tanzanian capture of Kampala in 1979 the American journalist Art Barrett discovered a copy of Coren's book on Idi Amin's bedside table.
