Warner Bros. is close to setting a female lead opposite Tom Cruise in the sci-fi thriller All You Need Is Kill.  Emily Blunt is in talks to pair up with Cruise in the film, which centers on a soldier in a war against aliens who finds himself reliving his last day over and over after being killed.  In the Source Code-ish story, Cruise’s character becomes a better soldier as a result of the time loop, as he’s essentially in an unending series of rounds of Call of Duty multiplayer.  If I’ve learned anything from COD, it’s that lots and lots of practice makes me slightly less sucky.  Hit the jump for more on All You Need Is Kill and the prospects of Blunt teaming up with Johnny Depp.In All You Need Is Kill, Variety reports that Blunt will be playing another soldier who fights alongside Cruise, but no other plot details are given.  Doug Liman (Jumper) is directing the adaptation of the graphic novel of the same name.  I’m a big fan of Blunt, and even though she killed in The Devil Wears Prada, it’s nice to see her stretching her acting chops across a variety of genres.  She starred alongside Matt Damon in last year’s sci-fi drama The Adjustment Bureau and will be seen later this summer in Rian Johnson’s time-travel pic Looper, and she recently starred alongside Ewan McGregor in the drama Salmon Fishing in the Yemen.Blunt’s penchant for sci-fi doesn’t mean she’s leaving her comedy roots behind, as she’s apparently turning heads in early screenings of Nicholas Stoller’s (Forgetting Sarah Marshall) romantic comedy The Five-Year Engagement alongside Jason Segel.  We recently reported that Blunt was one of many actresses being considered for Rob Marshall’s (Chicago) remake of The Thin Man starring Johnny Depp, and Variety notes that her strong comedic performance in The Five-Year Engagement has the studio placing her amongst the top choices.  Apparently Blunt, Emma Stone, and Kristen Wiig are the primary contenders for the role, as they're searching for someone with a strong comedic background who can hold her own. Whether she lands The Thin Man or not, it looks like Blunt has some great films on the horizon.
