Interesting.

How do we classify the 127 hours is a movie or a time value?

Reminds me of the "Shirts without stripes"

Edit: Removing that space between 127 and hours somehow makes it work. "how long is 127hours"

Sounds right to me. The vast majority of people are expecting the movie rather than the time period, so of course Google would show the movie's length.
