Now, months after promising fans production wouldn't move forward on the James Mangold

written and directed sequel until they had a "perfect" script, Jackman says the time is nearly here -- and he has the facial hair to prove it.

"We have a script. A full script," Jackman told Collider. "To tell you, two days ago I got that the full finished -- well, it's not finished, but we're getting super close, as you can see by the rate of my facial hair. That might give you a good clue that perhaps -- yeah, it's sooner rather than later.
