Wayland Town Crier 4/3/11: Film: Wayland author's 'Lemonade Mouth' opens wide. How sweet it was for Mark Peter Hughes as the Wayland author watched the film version of his book "Lemonade Mouth" for the first time at Showcase Cinemas De Lux at Legacy Place in Dedham last month. Hughes will be able to savor the experience again on April 15 when the movie is shown on the Disney Channel at 8 p.m. For an added bonus, he'll be watching the movie at Wayland Middle School, which is holding a special screening.
