"I could start to cry right now. It's an actor's dream," she said. "That is the pinnacle. That is what I thought had eluded me and here it is coming at a time, a very unexpected time for me, with a movie that my dearest friend wrote for me. Everything that's come out of this experience is just, heavenly."
"I would be incredibly excited, over the moon to get a nomination in that world."
But Janney isn't planning on stopping at an Oscar nomination and resting on her laurels.
"I just want to keep working, looking for great scripts, that's what excited me about this, I, Tonya," the 58-year-old said.
"I'm coming up on my 100th episode of Mom, which I continue to love to do," she added. "And we're celebrating that next weekend with Anna. So I'm really proud of that, so we'll see what's next. I'm open to anything."
"Anything" could also include a West Wing reunion or reboot. Janney was spotted on her co-star Joshua Malina's instagram for the TheWest Wing Weekly podcast, and noted that the Bartlet administration seems to be getting together pretty often.
"We've all been hooking up a lot lately, running in to each other," she said. "I'm never too busy for Aaron Sorkin and the cast of West Wing, I love them."
"We all need something to believe in. I'm in. If Aaron said jump, we'd all run," she added, referring to the possibility of a reboot.
It seems like if Janney wants to do something, she will. That includes rocking a silver sequin long sleeved, high neck gown on the red carpet that makes her feel like a downright boss.
"I tried this on. It's by Yanina Couture. I think the designer, after what was going on in Hollywood, she wanted to create a dress that was empowering and beautiful, and to me this felt like an incredibly empowering dress," Janney said.
"[It's] like my suit of armor. I'm Khaleesi's warrior shaman or something. I just feel like, you can't touch this!" she added.
But she admitted there's one accessory missing.
"No bird today, I wish I had the real guy, Little Man [from I, Tonya], but I don't know how he would do on a red carpet. He would probably fly away," she laughed. (She sported a fake bird on her shoulder in homage on the Golden Globes stage two weeks ago.)
