Never mind the top-billed Ronald W. Reagan; the real stars of Louisa are sprightly seniors Charles Coburn, Spring Byington and Edmund Gwenn. Spring plays Reagan's widowed mother, who is outwardly satisfied with her lot but inwardly lonely. Enter Coburn and Gwenn, who vie for Spring's attentions. Uptight Ronnie disapproves of his mother's dalliances, and has additional problems with his spunky daughter (Piper Laurie), who has just begun dating. Spring Byington and Charles Coburn worked so well together in Louisa that plans were made to star them in a weekly TV series. The project never sold, but Spring would star in a similar sitcom, December Bride, from 1954 through 1959. ~ Hal Erickson, Rovi
