Crowe, 51, said his parents opted not to baptize him so that he could explore his own beliefs, reported People magazine.
"From a young kid, I was quite interested in religion. When I met Tom Cruise when he was married to Nicole Kidman, we were spending a bit of time together so I thought I'd find out a little bit about what he was into," Crowe said.
The "Noah" actor said he then began his own research. "I found a video in the video store about Scientology and I watched it. It wasn't that informative. But I brought it up with Tom and I thought he was really cool.
But Crowe never ended up joining the Church of Scientology, in contrary to a recent report that named him a member.
"I never ended up putting my two cents down on anybody's table. I've never graced Scientology's doorway," he said.
