“Game of Thrones” star Alfie Allen and “Friday Night Lights” star Adrianne Palicki are among the new cast additions to Keanu Reeves-led assassin thriller “John Wick,” according to Deadline. Michael Nyqvist and Dean Winters have also joined the cast, co-led by Willem Dafoe.

Reeves plays the titular John Wick, an ex-hitman who goes after the guy that stole his car and killed his beloved dog. The thief turns out to be the son of a major New York crime boss, who in return hires Dafoe’s hitman character to kill Wick. Ouch, because the two used to be good friends but now have to “Mr & Mrs Smith” each other. Chad Stahelski & David Leitch are directing from a screenplay by Derek Kolstad, and there are no details on roles for the new cast additions just yet.

Allen plays Theo Greyjoy on HBO’s “Game of Thrones,” now heading into its fourth season. Aside from indies, his notable film roles include “The Other Boleyn Girl” and “Atonement.” Palicki played Tyra on critically acclaimed NBC series “Friday Night Lights” and was Lady Jaye in last summer’s “G. I. Joe: Retaliation.”
