Early in his career, Krims was a journalist with magazines in addition to writing novels and short stories. He became involved with films when Paramount bought the rights to one of his novels in the early 1930s and he went to that studio to work as a screenwriter. He went to work for Warner Bros. in the mid-1930s. While he was at Warner Bros., his contract allowed him to take leave to write for Collier's magazine, and in that way he reported on the Battle of Britain, the conference at Munich, and the Spanish Civil War. He returned to working for magazines in the 1970s, when he was film editor for Holiday and The Saturday Evening Post.
Krims was a member of the Army Air Corps during World War II.
The Academia Mondiale Degli Artisti Proffessionisti in Italy awarded him an honorary doctor of literature degree.
On July 11, 1988, Krims died of pneumonia at the Motion Picture Country Home and Hospital in Woodland Hills, California, at age 84.
