She made her film debut in 1913, and began using the stage name of Gladys Brockwell. She appeared in various shorts over on the East Coast before moving over to California where the action was starting to relocate.
Gladys appeared in the 1923 version of The Hunchback of Notre Dame with Lon Chaney. I had to include that because I am going to see the film later in October at the Redford Theatre. I didn't know she was in it, and so I am even more geeked now to see it! Yayyyy!!!
Now, she did make it in the business long enough to appear in talkies, and she actually did a good job in them...according to critics both then and now. Warner Brothers liked what they saw AND heard and they were lining up scripts for Gladys to look over.
Thomas Brennan claimed he had gotten something stuck in his eye which blinded him, hence the crash. He did sustain injuries, but he survived the accident.
Her last film, The Drake Case was released after her death in September of 1929.
Gladys was apparently married twice. First to director, Robert Broadwell and second to yet another director, Harry Edwards in 1918. The marriage was annulled the next year in 1919.
