The film was originally known as
Boy Meets Baby. In January 1942 Universal announced that it would be produced and directed by Henry Koster; Koster had directed most of
Deanna Durbin's films to date but this was his first as producer. The male lead would be
Bob Cummings and the script would be by Leonard Spigelglass based on a play by Régis Gignoux and
Jacques Théry. Universal wanted
Deanna Durbin to star but she was reluctant to make the movie. The studio attempted to borrow
Mary Lee from Republic but could not agree to terms. In March Universal cast Diana Barrymore who had just made
Eagle Squadron (1941) for the studio. The title was changed to
Love and Kisses, Caroline. The role involved the character having to play a 12-year-old girl, Sadie Thompson and Queen Victoria. Studio boss Cliff Work called it "the greatest part for a girl in 20 years." The following month John Boles and Kay Francis joined the cast.
Shooting Filming took place from April to July 1942. Koster said Barrymore "was a hard person to cope with. She meant well but I think she had some of the mental difficulties
her father had. She was always busy with other things when we wanted to shoot her scenes. Also it was not a good picture... They wanted to have a showcase for Diana Barrymore thinking that she might become a great actress. I don't think she had any of the Barrymore talent but she had the
Madame Sans-Gene attitude on the set and in her private life. She was, well, may I say the poor man's
Tallulah Bankhead."
Hedda Hopper visited the set to meet Barrymore. The day later Hopper wrote "Diana Barrymore is on the spot. With the great tradition of her family, she [Diana] can't behave like any other star out for a fling... She's likeable but has plenty to learn, and should stop playing around both on the set and in private life, which leads to those rumors floating around. No matter what Jack did, he treated the press as friend and she'd better change her tune – and quickly." Hopper also wrote about an incident on set where Barrymore chased her then boyfriend
Bramwell Fletcher all over the set to hit him."It interfered with the scene so Bob Cummings caught her and gave her a good sound spanking", wrote Hopper, "which delighted everybody on the set except for the youngest member of the Royal Family." In June the film was retitled
Between Us Girls. ==Reception==
