So here is a huge cake we made for a Hollywood-themed Sweet 16 birthday party. The party was held at the Hippodrome Theater in Gainesville so the setting was perfect!
For the cake, they requested large film reels topped with a director's clapboard:

Around each of the film reels, we attached edible photos of the birthday girl from the first 16 years of her life. Her mom gave us school photos, prom photos, dance photos, simple everyday photos, etc. They were great!

The clapboard was made of cardboard and completely covered with fondant. Then, I hand-piped the letters using yellow royal icing.

I love this cake. It would have been better to wait until the Oscars, right? Hm, Oh well. I'm just not that patient...
