- Joan Bennett, Maybe It’s Love, 1929. First choice Knapp became Bennett as the football flirt, enticing all the best players to her father’s Upton College in order to beat – at last! – its old rival. Extremely ho-hum.
- Louise Platt, Captain Caution, 1940. In March 1940, both Knapp and Diane Hunter tested for tackling the Anglo-American War of 1812 -1815. (Alan Ladd had a bit role).
