High Quality Content by WIKIPEDIA articles! Young Dr. Kildare is a 1938 film starring Lew Ayres as an idealistic but somewhat immature young medical doctor, who benefits greatly from the wise counsel of his mentor, Dr. Gillespie, a seasoned older physician. This was the second of a total of ten Dr. Kildare pictures, but the first starring Ayres (the character being portrayed by Joel McCrea in Internes Can`t Take Money), and the first to introduce the mentoring Dr. Gillespie. The series eventually continued with pictures centering around Gillespie once Kildare had been phased out.
