Miles Teller's grandparents inspired his work in Eternity

Miles Teller's grandparents inspired his work in Eternity.

The 38-year-old actor stars in the romantic comedy as Larry - a man who has to vie for the affections of his wife Joan (Elizabeth Olsen) after she encounters her first love Luke (Callum Turner) in the afterlife - and explained that his relatives were instrumental to his portrayal of the character as they stayed with him before filming in 2024.

Miles told People his grandparents: "It was really nice to just... I don't know, observe them.

"They're so in love. Oftentimes when people have been married for that long, when one goes the other - usually it's not far behind because that truly... it's like a broken heart kind of thing. So I just think it's really special."

The Top Gun: Maverick actor explained that his grandfather - who passed away in December 2024 - was particularly influential.

He said: "I come from a long line of great men, and so I'm proud to represent that."
