Select File > Save As...
Add "PDF" at the end of the file name, choose where you want it to save, than choose "PDF" as the Format.
Wait a few seconds while the conversion takes place.
Find the PDF you just made in Finder.

Once it is open, select View > Enter Full Screen
If there where any animations or videos, they will not show in this flattened version of the presentation.
