» Charlotte Greenwood as Brienne of Tarth

With her long face and prominent chin, Greenwood was not pretty in a conventional sense … — tcm.com.

… she was a tall, leggy gal who played second banana to the leading women of film, usually musicals, and Charlotte never got the man. — findagrave.com.

Greenwood was known mostly for her comic roles in both silent pictures and talkies, but I believe she was able to grab some serious roles too.  This idea came from twohandedengine and pitselly—thanks guys!
