According to "The Garner Files", the autobiography of James Garner, Garner once got into a physical altercation with Larson on the Universal lot. After Larson had copied a number of scripts from Detektiv Rockford - Anruf genügt (1974) and used them for his own shows, Garner's company complained to the The Writer's Guild who proceeded to fine Larson for plagiarism. However, this didn't deter Larson who then ripped-off the theme tune from The Rockford Files for one of his own shows. When Larson approached Garner and asked him if there were any hard feelings, Garner claims that he punched Larson so hard that it knocked him right across a curb, into a motor home and out the other side (The Garner Files, p.129, ISBN 978-1-4516-4260-5.).
