“I love her.

She’s one of my favorite characters I’ve ever played,” the actress tells EW.

“There’s just so much creative freedom; there’s no limit to her.”

“I was like, ‘Oh, am I going to be able to find her craziness?’

Because obviously we’ve grown and matured.

I was like, ‘Let me just feel this out a little bit,'” she recalls.

But as Povenmire noted duringa virtual Comic-Con panelfor the movie, “She just immediately hit this crazy stride.

Like, the very first thing out of the box was like, ‘She’s still in there.

You don’t have to look for her too far.'”

ASHLEY TISDALE:It felt so great.

We didPhineas and Ferbfor 10 years, the series, and it was really sad when it ended.

Because obviously we’ve grown and matured.

I was like, “Let me just feel this out a little bit.”

And within the first couple seconds, Dan and Swampy were like, “You are fine.”

[Laughs] But she’s such a great character to play.

I actually can’t do that; it doesn’t make me cry.

I think it was the same thing with those moments in this movie.

It’s just obviously in her voice, but a very real moment for her.

On the other side of it, you talked about going to this crazy place with this character.

Is there anything you do to get yourself into that and get into that headspace?

I think I just have probably a crazy side of me that I let out.

[Laughs] No, I mean, she takes up a lot of my energy.

I actually can only do two-hour sessions at a time playing Candace because it just drains me.

Her energy is just so wild.

But I love playing characters that I’m not like.

You’ve said before that you have an aversion to watching your past work.

I actually love watchingPhineas and Ferb.

I think it’s because I’m not seeing it when I’m doing it.

Because you record and you record, and sometimes we record in completely unorganized areas.

[Laughs] I just like to see how it comes out after the work you put into it.

Would you return to any of your other iconic Disney roles if the opportunity arose?

I don’t think so.

You know, you’re able to just be in your sweats recording.

So it is something that I’ve always enjoyed doing.

But I think, for me, I’m always looking to play different characters.

I don’t want to go too [far] back into playing stuff I’ve already done.

I want to keep growing as an actor, and keep doing things that challenge me.
