Rory McCann is a well-known actor who starred in the hit television series "Game of Thrones" as Sandor Clegane, popularly known as The Hound. He has shared stories throughout his career that illustrate the difficulties and unknowns that many new actors encounter when they enter the industry.

In one of his interviews, McCann spoke eloquently about early in his career when entering a movie set was like walking into a chasm. As he stood in front of cameras and seasoned actors he looked up to, he spoke of feeling overcome with fear and uncertainty. It was like entering a room full of professionals in your field when you're still learning the ropes.

McCann said he was unclear about who was responsible for what on set and whether those around him were truly impressed or just carrying out their duties. Regardless of their level of preparation, beginners often experience these emotions. Every move feels important, and you're not sure if people are watching you make mistakes. It's similar to being an amateur at a chess tournament where all of your opponents have been playing for years.

Anyone just starting out in their career can find solace in McCann's observations. They draw attention to how common it is to feel unqualified or confused among experts and stress the value of tenacity during those formative years. His experience shows that one can overcome these early obstacles and develop into a reputable professional with perseverance, practice, and time.
