Saoirse Ronan has tipped her father for a role in her film Mary Queen Of Scots.
The Hanna actress starred alongside dad Paul in Irish TV drama The Clinic, and in her new film How I Live Now, but each time, they have killed each other.
She r eckons it would be his turn to bump her off in the upcoming historical drama.
" Maybe I'll shoot him again (next time), maybe he'll shoot me. It's his turn. He could do it for Mary Queen Of Scots," she said.
Saoirse said of acting alongside her dad: "We've only done two little bits. The last thing we did together was the very first TV show I was in.
"They needed a man to almost knock me down in a car - clearly they thought my dad would be a good choice. So that seems to be the relationship we always have on screen. One of us is always killing the other one."
The 19-year-old is set to play the former Queen, whose reign on the throne was succeeded by Elizabeth I. She was later found guilty of plotting to assassinate Elizabeth, and was subsequently executed after 18 and a half years in custody.
"I'm doing it, whenever it happens. Hopefully it'll be next year. Susanne Bier is directing it. It would be really great if we could do it at some point," she said.
