The Professional Patient (1917)

Mr. & Mrs. Sidney Drew starred in a series of polite situational comedies, first for Vitagraph and then for their own company, releasing through Metro. Mr. Drew -- uncle of John, Lionel and Ethel Barrymore -- died after his son was killed in the first world war and his wife -- who wrote and seems to have directed a sizeable number of their comedies, starred. In this one, Mr. Drew has been fired from his regular job and, money growing short, takes up a position as a professional patient of a dentist, to reassure the other patients in the room. There he meets and falls in love with Mrs. Drew.
