Do you think the MM photos were done for their personal use…???? Because we haven’t seen these released in any way so why do them and then no one ever buys these gems??? They’re perfect, you would think it would have been a promo for something but NOPE. I bet a few are in their homes.

No, I don’t think so. I’d love to, but if they were personal they would have remained private. Actually they belong to Deadline, most of them, and they use them to illustrate all the articles they write about them since last year.
Mark Mann has been photographing a bunch of celebrities in Tribeca at the time he did this photoshoot. All the pics of other people look like the Gillian and David’s ones lighting and artistically-wise. They were taken for the Emmys section of Deadline, and I think Deadline wanted them in case they were nominated last year, which didn’t happen. Deadline didn’t buy them all, though so now Mark Mann is free to release the ones he hasn’t sold. He also personally sold a few himself. Last year, you could buy the one of my icon on his website for a few hundred of dollars. That couldn’t have happened if these were personal pictures. 
That said, I bet they have framed one or two at their homes too!
