On Tuesday, May 6, Focus on the Family will release the movie, “Irreplaceable,” for one-night showings in theaters across the nation.

The documentary follows Tim Sisarich of New Zealand as he explores two important questions: “What is family?” and “Does family still matter in today’s society?” (View the trailer.)

It was scheduled to be presented in more than 700 theaters, but pressure from gay-rights groups have led some theaters to drop the one-night showing.

Fathom Events, through its Digital Broadcast Network, is distributing the documentary. Tickets can be purchased online or at the box office. For a complete list of theater locations and prices, go to www.FathomEvents.com.

Experts interviewed in the film include law professor Helen Alvare, Carey Case of the National Center for Fathering, radio talk show hosts Michel Medved and John Stonestreet, author and speaker Eric Metaxas, British philosopher Roger Scruton, neuropsychologist Anne Moir, founder of “Brainsex Matters,” and others.

Former South Carolina senator and current president of the Heritage Foundation, Jim DeMint, said, “ ‘Irreplaceable’ reminds us why we must continue to cherish the unique value of a married mom and dad for a child and for all of society.”

Sisarch said his goal in the documentary was to find out whether the adage, “If the family fails, society fails,” is true.
