The Top Gun actor discovered Tom Hollander, who he appeared alongside in war movie Valkyrie, was planning to invest in a property but was unsure whether to go through with the expensive purchase.
Cruise was adamant his pal should commit to the buy, insisting he'd regret pulling out of the deal - and Hollander was delighted he ended up taking the star's advice.
He says. "It's very exciting because it's yet another situation where Tom Cruise is brilliant. I am not like him though I share the same name.
"We had one conversation on the set where I was just chit chatting about I was wondering about buying a house and I had been reading about sub-prime mortgages which I didn't really know what they were. I was a bit nervous about it and I thought maybe I should pull out and I told this to Tom really embarrassingly just as something to say.
"He went 'What you're gonna pull out, what's that? Buyer's remorse before you've even bought?' And I thought 'Oh yeah, I am such a loser I should be more like him.' So I rang my solicitor and said 'Buy it, buy it, it's fine Tom Cruise said buy it'."
