The lettering "Original Theatrical Edition" at the top of these has jaggies. Suggest using anti-alias on this lettering to avoid the jaggies.

Indeed you're right. I've stated some computer problems before, meaning I brought back these files from an ancient computer to a new one.

I didn't have this rudimentary font on the new one and then I had to work with flattened layers.

However, considering it's 300dpi, I doubt that it's going to be really spottable on the final print size. But yes, you're right. Fortunately, anyone bothered by this will be able to fix it for himself.
