Art Hansl finished his acting career on the Soap Opera, 'General Hospital'. He played a well-tailored detective lieutenant, pretty much the opposite of Colombo. This was a different form of the medium, being taped rather than filmed. Shot live and no retakes. Blow it and you go back and take it from the top. The alternative, of course, was to improvise because you didn't want to stop camera. Everybody did that, leading to some inventive dialogue.
