Collin Herth loves to play ping pong at 3 am in the morning

In a chat with HT City, Max Irons called the opportunity to share the screen with Firth a privilege. “He's one of the funniest, silliest, most playful men I've ever worked with,” he added. Irons revealed that Colin Firth “loves playing ping pong in hotel corridors at three in the morning, disturbing all the guests.”

Max says, “He’s (Colin) just so fun and he understands that to be an actor is to play and to be silly, to try and stay in that mindset and not to take it seriously. He's great. I loved him and it feels a real privilege to be with him.”

Max Irons says Mycroft is an important character in the Sherlock universe

Max Irons essays the role of Sherlock Holmes' brother Mycroft Holmes in the show, and he asserts Mycroft's importance in the Sherlock universe. He says, “I think Mycroft is a useful counterbalance to Sherlock. Sherlock, at this particular point in his life, is a bit anarchic, a bit unstructured and a bit of an agent of chaos. Mycroft, on the other hand, is a believer in being an agent for change within the system, within the constraints of the system.”
