Xoanon here,

After donning my Sherlock Holmes silly hat, my bubble pipe, and telling Calisuri that his new name is 'Watson', I've decided to post this.

I am officially conducting an investigation to find out who these 'mystery' cast members are. Harry, local patron at 'Ain't It Cool News' has informed his customers that 3 mystery cast members are 'IN these movies' no news yet as to who they are. But I will find out! Furthermore I will then post the information AND! (in my best Sherlock Holmes impression) provide information on said thespians.

Come along Watson!
