But tonight, the I, Tonya star has joined the best in the business as she takes away the Best Supporting Actress award at the 2018 Oscars for her portrayal of Tonya Harding's abusive mother. In past interviews, Janney has spoken about her sibling's long struggle with addiction that led to his suicide and inspired her to take a role in CBS's "Mom" as a mother who herself is an addict.
This was the first Oscar nomination and win for Janney, who has collected seven Emmys for her legendary TV career. "I did it all by myself", she said as the audience broke into a laughter. It got a significant laugh, but she quickly added, "Nothing further from the truth".
"My parents came to see me in everything I did growing up", she remembers. Other film credits include The Way, Way Back, The Help, Juno, Finding Nemo, The Hours, American Beauty, Nurse Betty, Drop Dead Gorgeous, 10 THINGS I Hate About You, Primary Colors, The Ice Storm, The Object of My Affection and Big Night.
After issuing her gratitude to several people, she dedicated the statue to her late brother, Henry "Hal" Janney.More news: Man shoots himself near White House
Her recently released movies include Tallulah, Miss Peregrine's Home for Peculiar Children, The Girl on the Train, Minions and Spy.
"This is for Hal", Janney said. She didn't want to go until she was nominated. "My fellow nominees, you represent everything that is good and right and human about this profession and you are all extraordinary", she gushed. With an arts background - her mother Macy performed in theatre; her father Jervis played jazz - Janney veered towards acting. "You're always in my heart".
In the run-up to the Oscars, Janney has been busy working on sitcom Mom, which has already won her two Emmy awards. "At a certain point I had given up thinking this could happen to me".
