I just liked the guy immediately, he has a big heart,” theCider House Rulesstar writes.

Anyway, weve been great friends ever since.”

Caine and Diesel eventually made a movie together in 2015:The Last Witch Hunter.

“My grandchildren, Taylor, Allegra, and Miles loved that film!”

“Vin really speaks to the younger generation.

Hes a real star, and multi-talented.

A fine producer who also writes scripts and gets deeply involved in the concept of his movies.”

“Whenever theyre in town, we have dinner together,” he notes.

“Or they come over to our flat for a catch-up.

Vin flies around the place with this traveling company of people a sort of mobile family and support structure.

Its certainly a change from my time.”
