The More The Merrier (1943) is a light comedy about a young Washington D.C. resident named Connie Milligan (Jean Arthur) who helps out the war-time housing shortage by subletting one half of her apartment to retired businessman Benjamin Dingle (Charles Coburn) who sublets half of his half to young Joe Carter (Joel McCrea).
Dingle plays cupid to the two young people, who exasperate each other, as comedy film couples often do.
TCM will show The More The Merrier (1943) Sunday March 8 at 10am EST.
