"[Pennywise] never gave me nightmares, but I've had lots of stress dreams about working in general and just being on set and doing something wrong and forgetting a line or something," Martell shares with Looper. "But as far as nightmares, I haven't had any about Bill Skarsgård."
In retrospect, Martell says he's come to appreciate Skarsgård's performance under the heavy prosthetics of Pennywise since his role in The True Adventures of Wolfboy required hours of prep and helped him develop a new acting discipline.
In the film, Martell plays Paul — a youth stricken with a rare malady that causes him to grow excess hair on his face and body — who embarks on an adventure to find his estranged mother when he receives a mysterious gift for his 13th birthday.
Also starring John Turturro, Chris Messina, and Chloe Sevigny, The True Adventures of Wolfboy is now available on video on demand.
