Never Been Loved
It was made clear to the actors that in a movie of this nature, there would be numerous love scenes to act out, and they were all mentally prepared for them.

The shooting then had to be stopped, and Roberts’ forehead had to be massaged in order to calm her down. But by this time, she had broken out into hives! Clearly, Julia Roberts still wasn’t used to the occupational hazards that came with the role of the leading lady, a role that many others considered to be second nature. Needless to say, shooting love scenes for Pretty Woman took up quite some time.
