This is the most Dad move ever.

Sebastian Stan looks a lot like young Mark Hamill, and the two Marvel/Lucasfilm stars have been having a lot of fun with the resemblance. Seb even had a mock audition for a Young Luke Skywalker movie. The two gents and their fans have enjoyed the back-and-forth banter, and the latest post from Hamill is pretty much perfect.

Sebastian Stan turned 36 on August 13, and Dad shared this cute message for his son:

Sebastian is apparently in Greece filming a movie, but he took time out to thank his fans -- and maybe his Hollywood Dad -- for their birthday notes:

We're looking forward to seeing more of Sebastian Stan's Bucky Barnes in "Avengers 4," which opens next May. And it was confirmed that Mark Hamill's Luke Skywalker will be back for "Star Wars: Episode IX," which opens December 2019.
