There's a ton of Coptic movies on YouTube, some of them are bad in production, others are pretty good in production. The last two that came out were of excellent quality. One was of a modern desert father, father Falatous of St. Mary's monastery in El Syrian.
This movie is about St. Cyril VI, the late Coptic patriarch's life in an abandoned windmill outside of Cairo. I believe it has English subtitles http://youtu.be/uqgG0Kt8YpU
Here's another movie about St. Cyril VI's full life. http://youtu.be/65e5D6lWh-0
Here's a movie about St. Mary of Egypt, which I thought was excellent. http://youtu.be/2-IgHyq07KA
Here's a movie about the life of St. Moses the black http://youtu.be/A2yv12fINdc
Here's a movie about the life of a monk who passed away in the 1920s, Father Mikhail of St, Mary's monastery el-behira http://youtu.be/snezCFcywuo
