In joke: While working in the pediatric ward, Tammy mixes up ID bracelets on babies, one of whom she identifies as "Bernard Schwartz", the real name of Tony Curtis, who Nurse Baxter mentions shortly thereafter in relation to the incident and who was then one of Universal's biggest stars.
Beulah Bondi and Margaret Lindsay had co-starred in The Under-Pup (1939): ''Tammy and the Doctor'' would be both actresses' final cinematic credit.
The sequence in which Tammy's plane arrives in Los Angeles utilizes the same soundtrack recording as the main title from Universal-International's remake, My Man Godfrey (1957).
