Though it was said to be written in just ten minutes, Bart Millard’s classic MercyMe’s song “I Can Only Imagine”—the subject of a forthcoming movie of the same name—was in reality “the result of a lifetime of experiences” which saw him overcome being abandoned by his mother and raised by an abusive father.

The movie releases in theaters March 16. The cast includes Dennis Quaid, Trace Adkins, Priscilla Shirer and Oscar-winning actress Cloris Leachman.
