LOS ANGELES (Reuters) – For most fans of “The Simpsons,” the name Nancy Cartwright may ring a bell as the voice of 10-year-old troublemaker Bart Simpson over 28 seasons of the Fox animated show.

Now, the actress is hoping to establish her own voice by documenting a surreal adventure, “In Search of Fellini.”

Cartwright, 59, co-wrote the new film, out in U.S. theaters this weekend, a mostly autobiographical tale of how her obsession with filmmaker Federico Fellini led to her own impromptu solo Italian adventure to find the elusive director.

“All the writers on ‘The Simpsons,’ they’ve created this legacy … and to be a part of that has been such a privilege,” Cartwright told Reuters.

“For me personally, I would like to be able to, as an artist, establish my own voice.”
