In Kill Me Three Times, Simon Pegg plays the competent, confident killer called Charlie Wolfe. So yes he's not a buffoon this time.
Stick with ius. He's a Brit working in Australia who gets hired to kill a guys wife (that's Alice Braga) to get some cash. But then some non-assassin sorts (including Teresa Palmer) get involved and it all pretty much goes to shit.
To whit, here's the Red Band Trailer for Kill Me Three Times.
Which looks like pretty decent stuff. It's nice to see Pegg in a slightly different role and the supporting cast look strong. The film has received great reviews since its premiere at the Toronto Film Festival in 2014 but is taking its time getting a release - its on VOD in the US in March, and comes out theatrically there on April 10th. There's no word on a Ireland/UK release just yet.
