Bob's Birthday -- Film Description:
"Surprise birthday parties can be risky. Especially when the guest of honour is turning 40! When Margaret plans a celebration for her husband, Bob, she underestimates the sudden impact of middle age on his mood. A witty, offbeat animated portrait of a frustrated dentist wrestling with the fundamental issues of life."
