Many thanks to Nic Iljine who shared the photo on his FB page. The gentleman with Keanu is Staffan Ahrenberg. Mr. Ahrenberg was the executive producer for Johnny Mnemonic.
If you are on FB, you can also read Mr. Iljine’s entry on the exhibit here. The photo is public right now but the exhibit info is not.
Note: This photo circulation on February 8 on twitter. The rightful owner was neither acknowledged or thanked by the person who posted the photo. The photo was also not sourced. Thanks to @LavenderFlo, that has been remedied.
