Regardless, experienced voice actors often get cast aside in favor of someone more famous when a big, important animated movie is made. The fact that celebrities can enjoy acting work without having to deal with costumes, script memorization, and travel to remote shooting locations and other elements of live-action filmmaking is another factor (although motion capture acting has many of those demands, and the actors behind these performances generally aren't considered only voice actors).

Maybe fans enjoy hearing a voice they recognize. Maybe the producers figure more people will see their movie if they can put " Taylor Swift" on all the posters in massive, gold lettering.

Celebrities do a lot of voice acting in big-budget animated movies.
