I interviewed at DAP Acquisitions (Chicago, IL) in December 2017. Interview I applied online through LinkedIn and got called back three days later for a first round interview.
Dean Martin played Matt Helm as Dean Martin. He wasn't the cold and ruthless Matt Helm of the books. Instead he was a cool and randy fella who loved to drink, seduce some chicks, croon some tunes & fight some bad guys. I wouldn't have him any other way.
According to The Complete Directory to Prime Time Network and Cable TV Shows (8th Edition, pg. 495), John Wayne was the first choice to play Marshal Matt Dillon, but he declined because he did not want to commit to a weekly TV series.
