Did You Know?


America Ferrera was originally cast as Mona Gray, but dropped out and Jessica Alba replaced her. See more »


When Alba was in class and put a child in a corner by the door she wrote two large numbers on the black board and wanted the children to tell her what sign (greater or less than) to put between them. When the child made a sound to get her attention you could see the less than sign already written on the board, but it was missing after the child from the corner gave the correct answer and the teacher wrote it on the board.

[first lines]
Mona Gray: [narrating] I used to love my dad's stories, until the one he told me on my tenth birthday.
Dad: There once was a kingdom where everybody lived forever. But the problem with nobody ever dying was that the kingdom got very crowded. And so the king, getting squeezed out of his own castle by his endless royal lineage, issued a decree.
King: [still-life cartoon] Everybody in my kingdom, please pick one person from your family to die. We will have a mass execution that will bring forth much-needed ...

If only it were Invisible ...
3 July 2011 | by twilliams76See all my reviews

An Invisible Sign is one of those films you kind of wish you had never seen. There are plenty of movies worse than this one; but this one tries so very hard to be both loved and cherished that it leaves one feeling used.

First-time feature-film director, Marilyn Agrelo (she had earlier directed the documentary Mad Hot Ballroom), uses so much saccharine in trying to sweeten Sign's audience into loving and liking and feeling for and/or sorry for this odd assortment of characters that one begins to wish strychnine had been used instead. In real-life, NONE of these eccentric characters would come across as likable and so one has to force himself/herself into finishing this film.

Jessica Alba (Fantastic Four, Sin City, Never Been Kissed) plays Mona Gray, an odd-duck of a character who is kicked-out of her house by her parents years after her genius mathematician father has suffered a nervous breakdown (she is kicked-out for no real reason other than she is 20 and her mom isn't likable). Lucky Mona, though (!), as her mother has helped get her daughter a job as the math teacher at the local elementary school ... Mona having no degree isn't a problem (Mom lied saying she had one) as the school never looks into her past (I'm not kidding).

It is at school/work surrounded by kids with greater problems than her own that Mona begins to wake-up to life and find purpose and meaning beyond a search for numbers. Mona also meets a fellow teacher played by Chris Messina (Julie & Julia, Monogamy, Vicky Cristina Barcelona) who becomes interested in her odd manners and seeks out her friendship. Just as these last few sentences suggest, An Invisible Sign IS oddly disjointed and filled with scenarios and situations that don't really go together. It is as if the film were pieced together because of "cute, little moments" ... instead of giving us a cohesive and plausible story.

There is little-to-no charm here and the entire thing feels tried and odd to me. I believe Messina's character was written/created for the sole purpose of having a sane individual in the film (yes ... groan). Alba has tried drama in the past and has come across marginally successful at times; but An Invisible Sign doesn't help her resume. It is almost too bad this one wasn't invisible.
