The 'secret' project came about in response to Jamie Campbell Bower's honest admission that the initial negative fan reaction got to him: "It's deeply hurtful" he said, in a interview with Collider.com (read the interview transcript here). From what I've read and seen, they could've cast a more perfect Jace. You can see how dedicated and committed he is to the whole project, it's almost palpable... like juicy mango (sorry, couldn't help referencing the Mango :P). My heart went out to him and it seems I wasn't the only one who felt this way...
Enter Fangirlish with Page to Premiere, TMI Source, Mundie Moms and Hypable who all came together with one purpose - let's show him the TMI fandom support him 100% and agree that #JamieIsJace! They all rallied the fandom and asked fans to send in photo's of themselves holding a sign, showing their support.
They received hundreds and hundreds of submissions! The first 300 or so were included in a video tribute which you can check out below. The rest of the photo's can be found here: http://mortalinstrumentslove.com/
Fangirlish will be putting together a photo album to be given to Jamie at ComicCon in July.
What a beautiful idea from a wonderful fandom to a well deserving actor :P
Here is the fantastic video tribute - Project Jamie is Jace:
