I don’t think a Presto feature would be such a great idea, either.
There’s just not enough to work with for 80+ minutes, but as a short it’s just perfect.
However, I do hope they sneak Alec into one of the upcoming features (TS3 maybe?).
Just feed him lots of chocolate and he’ll be happy to do a cameo. 
I agree with those who say it should stay a short, because mainly of the storyline’s restrictions - it can’t really be expanded after the short for up to 80+ minutes. That said, maybe Pixar can do an extra-long short feature to sneak into a DVD release, like, maybe, 20 minutes.
thats actually a really good idea Phileas! 
I personally didn’t care for Presto, so I wouldn’t want to see it as a feature-length film. As people have said, there’s just not enough there.
Presto would be a horrible feature film! It’s the type of movie that only works as a short.
Keep it as a short, and then everyone is happy. For example, shorts are meant to be short and sweet. Like you couldn’t take Boundin’, Geri’s Game, For the Birds, Luxo Jr. or anything like that and make it into a feature film. It just wouldn’t work.
And i know that this is off topic, but do you know that girl who died of cancer the night she watched UP? Well she also got an adventure book from the movie with the pictures of Carl and Ellie, and on one of the pages it said,“Thanks for the adventure, now go have your own.” Now the little girl’s mother has the book. Isn’t that touching?
