“9/11” (*** out of four) was a poignant melodrama set on the fateful day of 9/11/01 in which five people (Charlie Sheen, Luis Guzman, Gina Gershon, Wood Harris, and Olga Fonda) find themselves trapped in an elevator as they struggle to escape and survive and at the same time- come to terms with their lives and what is going on around them. A heartfelt tribute to those who gave all and those who lost everything on one of the most devastating days in American history. Sheen is unusually strong in a powerful performance. An interesting companion piece to OIiver Stone’s “World Trade Center.”
