Keanu Reeves may be used to playing a fearless hero onscreen but, in real life, the actor is certainly not immune to fear.

After suffering two different home intrusion last month at his house in Hollywood Hills, Calif., the "John Wick" star opened up to fans about the frightening events.

"Yeah, I guess my security wasn't good enough...it's better now!" Reeves told his fans during a Reddit AMA on Monday.

"And, uh, it was really scary," he explained. "The first time was at like 4 in the morning on a Saturday, and it was scary."

Scary indeed! A spokesperson for the Los Angeles Police Department reportedly told E! News that the second intruder, a woman around the age of 40, was apprehended after taking a shower inside Reeves' home and going skinny-dipping in his pool.

Switching to a lighter subject, when Reeves was asked who "the biggest movie star" he would consider a friend was, the actor answered, "The biggest movie star I'm friends with would be... uh... Sandra Bullock! Yeah, through the years we kinda get together, have a dinner, catch up, see how it's going."

He fondly recalled a day during filming "Speed" with Bullock that helped bond the pair.  

"They let us drive down the street smashing through cars on the bus. And everyone started to scream, hehe, and then laugh when it was over, and it really bonded everyone together," he wrote. "It was early on in the filming, yeah, but it was really fun to be smashing through cars!"

While Reeves new film, "John Wick" opens in theatres on Oct. 24, it's the potential sequel to his cult classic film "Bill & Ted's Excellent Adventure" that really has fans buzzing.   

"We have to get the script in the right place," Reeves told Comingsoon.net in an interview about the possibility of "Bill & Ted 3." He explained that the beloved main characters would have to have a reason to go on another onscreen adventure. "What is the reason to make this movie besides nostalgia or the love of these characters. Where can they be in their life that can be a story that is worth telling or has something in it and is funny?"
