It’s possible that Hugh just took the opportunity of having Ryan Reynolds in the room to make something funny for whoever he wanted to wish a happy birthday.
Whether this was really part of an attempted birthday message to a friend or just an excuse to post a funny video with Hugh Jackman and Ryan Reynolds isn’t clear, nor does it matter, because it’s hilarious.
It seems that this video was filmed in the same room following the one shown at CinemaCon.
