If it's the TV edit, it will be nearly 3 hours log and have a dreadful illustrated still art at the beging talking about the Butlerian Jihad for 20 minutes. It's awful and got the Alan Smithee treatment by the director (for very good reason). The TV edit is a hard watch.

The theatrical release is awesome and 2 and a half hours long. Princess Irulan opens with a bizarre monologue that fades her in and out. The movie is underrated because it's clearly 2 movies crammed into 1 (entirely the fault of Dino De Laurentis) but it's worth watching. The music, the acting, the wonky ass special effects - it's all mesmerizing even if it isn't consistently good. But at times it's fucking awesome and worth the watch.

Here's hoping we get the original theatrical cut!
