Warner Bros. has released the first Run All Night trailer. Liam Neeson reunites with his Unknown and Non-Stop director Jaume Collet-Serra to play an aging hitman who, in order to protect his son, must take on his former boss in a single night.  Despite the self-serious rendition of "O Danny Boy" that kicks in on the trailer about halfway through, the film actually looks pretty good.  It could just as easily been called "Dangerous Dads" given the central premise at hand, and while Neeson's been starring in a number of same-looking thrillers for the past few years, this one at least has a hook: the entire movie takes place over the course of one night.  But the most important thing here is that Run All Night is a film that's essentially Liam Neeson vs. Ed Harris.  That's all we really need to know.

Hit the jump to check out the Run All Night trailer.  The film also stars Ed Harris, Joel Kinnaman, Common, Vincent D'Onofrio, Holt McCallany, and Beau Knapp.  Run All Night opens in theaters on February 6th.

Here's the official synopsis for Run All Night:

Brooklyn mobster and prolific hit man Jimmy Conlon (Neeson), once known as The Gravedigger, has seen better days.  Longtime best friend of mob boss Shawn Maguire (Harris), Jimmy, now 55, is haunted by the sins of his past—as well as a dogged police detective (D’Onofrio) who’s been one step behind Jimmy for 30 years.  Lately, it seems Jimmy’s only solace can be found at the bottom of a whiskey glass.

But when Jimmy’s estranged son, Mike (Kinnaman), becomes a target, Jimmy must make a choice between the crime family he chose and the real family he abandoned long ago.  With Mike on the run, Jimmy’s only penance for his past mistakes may be to keep his son from the same fate Jimmy is certain he’ll face himself…at the wrong end of a gun.  Now, with nowhere safe to turn, Jimmy just has one night to figure out exactly where his loyalties lie and to see if he can finally make things right.
