The Huffington Post states: "Costello, a brilliant comedian.”

At five feet three inches tall, Sue Costello may be petite, but she is powerful when it comes to bringing the funny. Sue’s power, mixed with her vulnerability, makes her distinct and approachable at the same time. From her Boston accent to her “tell it like it is” demeanor, you can’t help but feel like your laughing with your best friend.

After starring in two TV pilots for CBS, Sue was the co-creator of her very own self-titled television series, Fox's Costello, in which she was also a producer.

As an actress, and in addition to her television appearances, Sue has also honed her performing skills on the big screen. She was cast in such films as the Academy Award winning The Fighter starring Mark Wahlberg and Christian Bale, directed by David O. Russell; Southie starring Donnie Wahlberg, directed by John Shea; and Once in the Life with Laurence Fishburne. Sue also just wrapped filming on the movies The Witching Hour co-starring William Forsythe and Michael Madsen and Best Man In The Dark.
