He voiced the adult Cornelius Robinson in the 2007 Disney animated film Meet the Robinsons (where he was the basis for a joke at one point). He also played Peter Mitchell in the 1987 Touchstone Pictures film Three Men and a Baby and its 1990 sequel and James Rainwood in An Innocent Man.
- Selleck was originally cast as Indiana Jones in Raiders of the Lost Ark by Steven Spielberg as George Lucas didn't want to gave the role to Ford due his past collaborations in the past. However, CBS obliged him to pass the role due his contract and Ford was finally cast instead. Oddly, the pilot of Magnum was delayed from March 1980 to December of that year, which would have allowed Selleck to film Raiders between June and August of that same year in Tunisia and later return to the United States to film Magnum.
