Matt Helm is a fictional spy who was portrayed by American actor Dean Martin.
While Cate Archer was infiltrating the Dumas Towers in England, she overheard two H.A.R.M. guards talking about various spy films they had seen including The Silencers and The Ambushers. One guard was not impressed as Matt Helm didn't do it for him.
- This conversation was a tip of the hat to the 60's Spy-Fi era that influenced The Operative: No One Lives Forever.
