Richard Linklater’s films are defined by conversation, by what’s said and what’s not. The filmmaker is often interested in how discussion can encourage movement, each thought leading to a new idea or revelation. It’s that sort of conversation that’s at the heart of Last Flag Flying, the director’s latest project, adapted from Darryl Ponicsan’s 2005 novel of the same name. His 2005 novel is a sequal to 1970's The Last Detail, which was made into a movie starring Jack Nicholson in 1973. Made more than 40 years later, Linklater’s thoughtful rendition is not so much a sequel as it is a companion piece, reimagining the characters in a way specific to this work.
