Door to Door (2002)

Bill Porter is a cripple, handicapped since birth. His rather wealthy ma drives him around to indulge his ambition to become a door to door salesman. After endless refusals at sight, he is granted a test period on Watkins's worst round, and somehow survives, probably due to his good-mannered helpfulness as much as tireless persistence, becoming a trusted household adviser for lonely people. During his ma's senility ending in death, a Mormon couple helps Bill out, but his pride gets in the way of accepting, leading to a battle of charity.
