Not to be confused with the silly reality TV production with the same title, The Trench, with a just-on-the-verge-of-stardom Daniel Craig in the lead, captures the claustrophobic feeling, tediousness, and random danger of trench warfare better than any film I've seen. The 1999 movie, set in the days just preceding the Battle of the Somme, was written and directed by WWI author William Boyd operating on a low budget. Maybe because of this, except for the concluding and somewhat predictable over the top sequence, the entire story is set in the frontline trenches and dugouts. Yet the dramatic result is most effective.
By the end of the 98-minute production, the viewer is left with a sense of having spent a long stretch in a linear, open-air prison. The personalities of the soldiers are well explored, but at the center of everything is Sgt. Telford Winter (Craig). One of the things I especially liked about The Trench is the depiction of how it's the sergeants who actually run things at the cutting edge of any combat operation. Winter, burdened with a weak and erratic lieutenant (nicely portrayed by Julian Rhind-Tutt), carries a bigger load than most NCOs. The film is available on Netflix and for purchase on Amazon.
