Thanks to fellow Whitney fan and twitter follower @WHFan I found out that you can hear Whitney's voice singing "I will Always Love You" in the trailer of The Hitman's Bodyguard Red Band trailer starring Samuel L. Jackson and Ryan Reynolds.
The film is about the world's top bodyguard getting a new client, a hit man who must testify at the International Court of Justice. They must put their differences aside and work together to make it to the trial on time.
I guess they wanted to use Whitney and play on the whole Bodyguard theme. It works! I love anytime we get to hear Whitney's voice again. You can fast forward to the :54 second mark to hear Whitney belt out that timeless lyric "And I Will Always Love You!"
