 Grant had been working on this acting persona for some time; McCarey merely made Grant think more precisely about what he was trying to accomplish on camera.Additionally, McCarey worked to give Grant comic dialogue and physical comedy (like pratfalls) as well as sophisticated dialogue and urbane moments, efforts which Grant also deeply appreciated.Over time, Grant came to feel liberated rather than inhibited by the lack of a script, and seized the chance to make sure that the film's humor reflected his own.
