Ah, the old 'wrestlers cant act' stigma rears its head again - it's surely a sweeping generalization, no? Are you saying that there has is not, has never been and never will be someone who has worked as a professional wrestler who has shown some kind of acting ability worth a damn? Because I could name a few undertakers, waiters/waitresses, sales assistants, cooks, milkmen, hell, guys dressed as chickens who were probably told the same only for them to become some of the most highly regarded and successful actors ever.
Yes, there have been some awful wrestlers turned actors in the past but equally, there are terrible actors out there who never set foot in the 'squared circle' - being a bad actor is not mutually exclusive to wrestlers and the likes of Johnson, Cena and Batista are showing that. But yeah, lets just say that they are all terrible and if it shows on their CV that they were a wrestler at any point in their life reject them for an audition.
