Over the past few years, Jackman and his wife, Deborra-Lee Furness, have been to the Oscars a few times. In 2011, Jackman served as a presenter, and in 2009, he took on the job as Oscar host.
But it's a different feeling coming in to the event as a nominee.
"I talked to Russell Crowe about it, and he said, 'Man, I don't care who you are, the floor falls from you,'" Jackman said. "So I've taken that to heart. If it happens, you won't see me stand straight up. I'm just going to sit for a bit."
The 44-year-old actor says his wife doesn't get intimated with him working with actresses like Halle Berry, Nicole Kidman and Anne Hathaway.
"They meet me and we work, and it's fine. But as soon as we have a dinner and they meet Deb, they don't ever want to talk to me again because she's way more interesting, way funnier, way sexier," Jackman said. "So it is all about Deb and rightly so."
Jackman says his dad is flying in for the Oscars, "so regardless of what happens, it's going to be a special night."
