The younger Irons, whose mom, Sinead Cusack, is also a screen star, is adamant fans will never see him share scenes with Jeremy, as a father-son collaboration would be "really difficult."
"That's my nightmare. My mum maybe, but my dad ... that would be really difficult. Have you ever met him? He's a force of nature, I'll put it that way; he likes to make his voice heard on set, and I wouldn't be able to disentangle father and actor," he told Britain's Independent on Sunday. "No, keep well away from that."
The 27 year old also refuses to sign up for big-budget Hollywood movies just to boost his profile, adding, "Since 'X-Men,' our perceptions of what success is have changed. You hear of people my age earning $10 million on their second movie, and that's what we perceive as success ... There was a franchise that came in my direction and I said, 'I can't do it,' and my agent said, 'No, you need to do this, it will add another zero to your pay,' and I said, 'No, I can't. If I do it, I might want to give up.'"
Jeremy Irons carried The Borgias miniseries on his BACK, and without him it would have been just a disgusting slasher movie with costumes. Of course, a lot of the story was devoted to his dealings with his unruly children, so maybe he used his own experience.
