Tom Cruise -- My Job's As Hard As Fighting in Afghanistan

Cruise's lawyer, Bert Fields, says the notion that Tom compares his acting to fighting a war is a distortion, pointing to a section in the deposition -- not part of the deposition that was publicly released -- in which Tom is asked, "Do you believe the situations [being in a movie and fighting a war in Afghanistan] are the same?" Tom replies, "Oh come on." Fields says that clearly means "of course not."

For the record, here's Tom's quote, responding to the opposing lawyer in the deposition:

Lawyer: "Now, your counsel has publicly equated your absence from Suri for these extended periods of time as being analogous to someone fighting in Afghanistan. Are you aware of that?"

Cruise: "I didn't hear the Afghanistan, but that's what it feels like, and certainly on this last movie, it was brutal. It was brutal."

Tom Cruise not only thinks he trains harder than Olympic athletes, he believes his job as a professional actor is as grueling as fighting the war in Afghanistan -- this according to legal docs obtained by TMZ.

As we reported, Cruise recently sat for a deposition in his $50 million libel suit against a magazine publisher that claimed he abandoned daughter Suri -- and his quotes are GOLD.

First, the Middle East -- Tom says his location shoots are just like serving a tour in Afghanistan, "That's what it feels like. And certainly on this last movie, it was brutal. It was brutal."

As for his physical training, Tom said, "There is difficult physical stamina and preparation. Sometimes I've spent months, a year, and sometimes two years preparing for a single film." But the kicker, he adds, "A sprinter for the Olympics, they only have to run two races a day. When I'm shooting, I could potentially have to run 30, 40 races a day, day after day."

But it's not all grenades and triathlons ... Tom says he's only flown commercial ONCE in the last 4 years ... and that was because he had no choice.
