Sounds like the set of Liam Hemsworth's new corporate espionage thriller Paranoia was a real riot!

The film, featuring the Australian actor as a tech whiz looking to get ahead in life, features some steamy love scenes between him and costar Amber Heard—but it turns out that the crew wasn't always interested in getting the shot down in one take.

"I get into the bed and they say 'action,'" Hemsworth recalled one particularly hilarious (or traumatic, depending on who you ask) day on the set. "And then I turn over and I grab what I thought was her arm, and it was a giant dildo."

"It was about that big, a black one," he added, holding his hands nearly 2 feet apart. "And I pulled it out, and everyone was in on it...except me, yeah."

Please say they got that on camera for the DVD outtakes...

Meanwhile, Hemsworth also dished about being an uncle ("It's so odd to me, still, that my brothers have kids") and about wanting kids of his own one day ("One day, but it's not on my to-do list right now"), and he told us a hilarious anecdote about trying to crank out his first tweet when he finally joined Twitter not too long ago.

"I sat there for about 20 minutes and was like, 'God, what am I going to write? Why would people care what I write?'" he recalled.

And "all these comments say that I suck at tweeting. I don't even know how you could be bad at tweeting!"

Watch the clip to hear all of Hemsworth's adorable anecdotes with an Australian accent—and don't miss the end, when Heard pops up to talk about how she maintains her private life!
