Andrew Robinson

Andrew Robinson wrote and directed 'April Showers.'

It’s been 10 years since the massacre at Columbine High School in Littleton, Colorado, left 12 students and a teacher dead. I couldn’t believe it when I saw the date. April 20, 1999, is a date no one watching the events unfold will forget. And, as we’ve sadly seen, it wasn’t the last school shooting, with the Virginia Tech shootings and others that followed.

Andrew Robinson wasn’t watching the news from afar like most of us. He was there. Living it. Smelling it. And running from it. Andrew was in the computer lab in the middle of the campus when the shooting started. He ran to physical safety, but the days and years to come proved to be emotionally perilous.

Andrew wasn’t a filmmaker in Los Angeles, California; he was in advertising. But he sat down to write a story based on his experience at Columbine, and the screenplay for “April Showers” was born in three days. That’s when Andrew realized: “Wow, that’s been in the back of my head for all these years.” He says those years brought about side effects rarely seen in the media: guilt, community persecution and the post-traumatic stress disorder. “I’m just trying to share what I’ve learned so no one else has to go through it,” Andrew says of the goal of his anniversary film.
