"I am a homebody, so when I escape, I wouldn't want to go anywhere except my own little house," she says. "With my own little thoughts, my own little corner, and my own little chair."
She's earned both an Emmy and a Golden Globe for her role as trash-talking cheerleading coach Sue Sylvester on the hit Fox show, and she also lends her famous voice to the animated film Wreck-It Ralph, which is up for an Oscar this year.
The actress has hit her stride with animated roles. She voices the character Io (a one-eyed alien who struggles with anger management issues) in the new animated flick Escape From Planet Earth, which opens in theaters today.
Lynch spoke to PARADE about playing angry characters, Glee's future, and more.
On comparisons of Io to other characters she has played.
"The thing that distinguishes Io from Sue Sylvester and anybody else I've played who has anger management issues is that she's really struggling to control it. She's a very earnest and really grateful to Craig Robinson's character, the mouse alien [Doc], and she's trying her best."
On identifying with her characters' personalities.
"I don't think I can play it if I don't. It has to be in me somewhere, absolutely. I have a quick temper, but it's over fast. I always feel shameful at the end of it—the same way Io does."
On working with her Planet Earth costars in the recording studio.
"The only time I spent time with them was on the red carpet at the premiere, so it was really nice to see them. If I didn't know them personally, there were a couple degrees of separation between us. I know Craig, I know George Lopez, I know Rob Corddry and so it was really nice to see Jessica Alba and all those people I've met before."
On Glee's season finale.
"We haven't [gotten to it yet]. I think the writers know where we're leading up to. Ryan [Murphy] works that way, he has an arc for the season. I haven't had my ear to the ground. I'm always the last to know everything. I was on the set when Ricky Martin was there and I was like 'What is he doing here? This is so wonderful!' He said, 'Jane, it was announced three weeks ago.
