I hadn't looked at Mugglenet recently so I checked it today. Evidently, they still haven't cast Young Snape. And IMDB lists the status of OotP as "Filming."
...if they've changed the Penseive scene so Harry still gets to see his asshole dad but we don't get to see young Snape, I'm going to start smashing things. The only possibilities I can think of are 1) they're planning on filming it later and they're still looking, 2) IMDB hasn't been updated yet and they have cast someone or 3) they're changing the way a Penseive works and we're going to see Snape's memory from a first-person POV, therefore we don't get to see what he looks like (assuming he doesn't walk past a reflective surface). Dammit, I want to see young Snape! And old Snape. Just "Snape: The Movie" would be fine with me.
There's no young Lupin in the list either. What the hell, man? How am I supposed to make up slash stories in my head where AU Snape and Lupin become friends in their first year and Lupin isn't friends with James & Sirius if young Snape and Lupin aren't even in the movie?!
