Hammer is convinced the film industry is a cold-hearted business and has joked that his co-star wasn't prepared to give him advice in case he snapped up some of his desired roles in the future, reported Contactmusic.
"I was definitely taking notes and watching but never at any point did they say, 'Come here, youngster, come sit on my knee and I'll spin some yarn for you.' This is a very cold-hearted business. I think people would rather just stab you in the back. Johnny's very intimidated that I will end up stealing his jobs," Hammer said.
