Susan Kohner Marriage details

How does one correct marriage details in a biography?  I'm watching "To Hell and Back".  Susan Kohner has a small role in the movie.  I was looking up details on her on IMDb.  In the biography section she is shown as married to a fellow John Weitz who is young and current.  The John Weitz Kohner was married to was a designer and died in 2002.   The entry in the line below is incorrect.                                                                                                                                                                                                                                                                                                                                                                                                                                                        After appearing in Freud (1962), Susan left films for good with the exception of appearing in the television program Temple Houston (1963) in 1963. She wed John Weitz in 1964 and retired to raise a family.
