They had no idea what they were in for!
On Monday night, Fox held events in New York and Los Angeles that were advertised as showing "first-look footage" of the upcoming comic book flick Deadpool.
But crowds were shocked when Ryan Reynolds himself showed up at the event in NY, while LA fans were surprised by Stan Lee, T.J. Miller, Brianna Hildebrand, Deadpool creator Rob Liefeld, and screenwriters Rhett Reese and Paul Wernick!
And in a bold show of confidence, Fox showed the ENTIRE movie to all the lucky people in attendance!
For those that don't know, that's pretty much the opposite of what they did with critically panned Fantastic Four, which embargoed reviews until 24 hours before the release!
But with this movie, the studio even let fans go on Twitter to share their early reviews — and it was an unfinished version of the film! Talk about guts!
