When Tony Musante agreed to do the series, he refused to commit to more than one full season. He would continue in the role only if the second season was shortened to 10 episodes, or six 90-minute 'wheel' episodes, as was used on the The NBC Tuesday Mystery Movie (1971). Producers were certain Musante would change his mind, and return for a full second season, so they agreed to the unusual contract. But when the producers tried to renegotiate with Musante after the first season, he still refused, and quit the series. The producers wanted Robert Blake to take over the role. But when Blake balked at taking over an established role, the series was retooled as Baretta (1975).
