Own the rights?
I'j not a big fan of thriller plays (and I've acted in this one), but well-made with superb casting - mainly Ms. Hepburn & Mr. Arkin with gliding, smooth support from Mr. Crenna & Mr. Weston; superbly lit with a great set and menacing music, it was Hepburn's last film for nine years and she should have won Best Actress (nominated), and I pick Bonnie & Clyde to win ALL the other categories (acting-wise), she kicks into gear and then retires..until ROBIN & MARION nine years later.Anyway, most stage-play thrillers don't make it on FILM, but this one is very claustrophobic and believable because of Hepburn (who studies with blind people for a while). Turn the lights off ..like they did in the last 8 minutes in the theatre when it opened in '67!
