Though Janssen's scenes were cut from the final release, he also appeared as a journalist in the film "Inchon", which he accepted to work with Laurence Olivier who played General Douglas MacArthur. At the time of his death, Janssen had just begun filming a television movie playing the part of Father Damien, the priest who dedicated himself to the leper colony on the island of Molokai, Hawaii. The part was eventually reassigned to actor Ken Howard of the CBS series "The White Shadow".
