If you saw "Life" this weekend (and if you didn't, well, you should), you know that the movie has some pretty big twists. In fact, it's bookended with them. And we're going to talk about them. So if you haven't seen the movie, then shoo. We got this.

Seriously, if you haven't seen the movie please don't read this. Come back afterwards; it'll still be here.

All right, so the movie opens with the crew of an international space station uncovering some Martian soil, which produces an honest-to-goodness Martian. Earth is alerted, everyone rejoices. Except that this Martian isn't as cute and cuddly as it seems, and pretty soon it's growing at an exponential rate and murdering crewmembers. You know, that old killer-space-beast chestnut.

The shocking thing is who goes first, though. It's Ryan Reynolds, a person so unnaturally handsome that you assume he's going to make it until the end credits. (Maybe that "and Ryan Reynolds" distinction on the poster gave it away, though.) When we talked to director Daniel Espinosa about the twist, he said it was one of the things that drew him to the project, and referred to Reynolds's death as his "Janet Leigh moment," referencing the shocking death at the beginning of Alfred Hitchcock's "Psycho."

When I talked to the writers (Rhett Reese and Paul Wernick) about the movie, just before its world premiere at SXSW, I had to ask them about what it was like murdering Reynolds so early.

"We tell people Ryan's our muse," Wernick said, sweetly. "We always have him in mind when we're conceiving and writing projects, and it's so great to continue our partnership with Ryan, which has lasted since 2009. We've worked hand-in-hand as one creative voice." Reese then piped in: "They say kill your darlings. Well, we killed our darling." There was a pause and Wernick added, "We can't kill Ryan as Deadpool because he's un-killable, but we can sure kill him in 'Life.'"

Sorry, Ryan. :(
