I believe this is by Franco Saudelli https://www.stripinfo.be/auteur/index/877_Saudelli_Franco - however, I am not 100% sure. Dude doesn't sign his work apparently.
Yes, it's Saudelli. The story was originally published in an italian comic magazine called "Orient Express" issue #30 (original story title: "A come Attore" i.e. "A for Actor").
