As an actress, Jerry Hall started out treading lightly rather than overtly capitalizing on her modeling celebrity, appearing in small roles on film and honing her thespian skills in small stage productions.
You may be aware, for example, that she made her London West End debut playing Cherie in a production of William Inge's Bus Stop in 1990. What you may not know is that she'd tried out the role in a 1988 production at . . . Montclair State College (now Montclair State University) in New Jersey, two years earlier. So she was ready for London.
She also played Mrs. Robinson in a Broadway production of The Graduate. :-D
It makes sense that Jerry Hall would play a middle-aged seductress, because she still remains seductive in, as of this writing, her late fifties (she turned 59 years old on July 2, 2015). The picture above and the picture below are both from 2014.
And, oh, yes, "Jerry" isn't short for Geraldine or anything like that - it's actually her birth name. :-D
