Refine the question. Pangram film lists rely heavily on vowelless titles to soak up the excess of consonants, and the 5-lists are no exception. If there are only 5 film titles, their average length is more than 5, so the average length of those that have vowels is greater still, reducing choice. One idea that helps to make a list with few films is to use as long a title as you can find. I will show that, even if this title uses many vowels, this might not be a disadvantage.
Slavic languages are examples.
Those that use the Cyrillic alphabet are transliterated as necessary. It helps that those that use the Roman alphabet sometimes use R and J as vowels. Here are some 5-lists. Note that each title in the Max Q list has 4 or more letters. Here are some examples, again arranged by Q-title.
