This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. The 失 gets shortened, and 敗 gets rendaku'd, though. Don't make that 失敗.

To be honest, this movie you made is a flop. However, you can’t let it get you down just because you failed once. Someone said that success is the ability to go from one failure to another with no loss of enthusiasm, right?
