Every wonder if you really know your closest friends? Everyone has their own secrets that even their closest buddies don't know..

This is what the Cinemalaya 2012 entry "Mga Mumunting Lihim" is all about. Direk Joey Reyes was present during an intimate talk with some bloggers and talked about his Cinemalaya entry. He mentioned that some portions of the film where based on true accounts of his friendship with his bestfriend who passed away years back. 

"Mga Mumunting Lihim" was actually his (Direk Joey) second entry to the Cinemalaya. When he got a go signal that the script got approved, he immediately started casting. First to be asked was Judy Anne Santos who didn't hesitated to yes for a "kontrabida" role. Eugene Domingo was supposed to be part of the main cast but due to her hectic schedule of "Ang Babae sa Septik Tank" showing in various festivals abroad, she had to decline the offer. Compleying the cast were Iza Calzado, Janice de Belen and Agot Isidro. 

The death of Mariel (JUDY ANN SANTOS) was met with such hurt by her three closest friends. But it was her best friend, Carla (IZA CALZADO) that she leaves a most special gift, a box full of her diaries through the years. Carla has been Mariel’s friend since their high school years; they have practically shared everything in their lives together. Their two other girl friends, Sandra (AGOT ISIDRO) and Olive (JANICE DE BELEN) formed the quartet who would get together ever so often and served as a mutual support system. 

Despite warnings from Sandra and Olive not to read the diaries left behind by Mariel, Carla could not help herself to find out what was written on those volumes of handwritten materials. True enough, what she discovered completely shattered all her perceptions and beliefs of the friendship shared by the four women through the years. Inside those diaries were all the little secrets that the women kept from one another---all the hidden emotions, stories and comments that made their lives a sham. Death should be a closure but it could also be a terrible beginning and realization of what was hidden by the living.
