A friend and I are currently brainstorming ideas for a little game project we have in a few weeks and one of the ideas involves using two currently alive celebrities as the protagonists.
The game isn't going to be a AAA title, it is going to be a small game consisting of 8bit graphics. However, we will be modelling the graphics off these two said celebrities and in addition we are also planning on using one of the celebrities names in the title of the game which we would put on the android app store. Another point to add is that we are planning on monetizing the game. It also might be worth a mention that we live in the UK and the celebrities in question live in the U.S.A
So given the above - Is it legal to do what we are proposing? And if so are there any 'catches' if you will?
I look forward to any and all help!
(I did not know what area of law this would fall under, so apologies if I used an incorrect tag)
