The Caretakers (released in the UK as Borderlines) is a 1963 American drama film starring Robert Stack, Polly Bergen, Diane McBain, Joan Crawford and Janis Paige[4][5][6] in a story about a mental hospital.

The screenplay was adapted by Henry F. Greenberg from a story by Hall Bartlett and Jerry Paris[4] based on the 1959 novel The Caretakers by Dariel Telfer.

Patients include distraught mother Lorna Medford, former prostitute Marion, pyromaniac Edna, and former schoolteacher Irene.

[9] Crawford was on the board of directors of PepsiCo, and product placements for Pepsi-Cola include a scene at the hospital picnic, which features a wagon that is dispensing the soft drink.

[citation needed] Variety wrote "Miss Crawford doesn't so much play her handful of scenes as she dresses for them, looking as if she were en route to a Pepsi board meeting", and called the film a "superficial, ineptly-plotted drama"[10] Bosley Crowther of The New York Times noted "Altogether, this woman's melodrama is shallow, showy, and cheap - a badly commercial exploitation of very sensitive material.
