Sometimes we forget that not every hot shot in Hollywood knows one another. It's why your favorite actors and directors don't work together on every single movie. It's why fans haven't gotten, say, a brain exploding awesome film starring Dwayne "The Rock" Johnson and directed by Steven Spielberg.

But at least that pair has opened up a line of dialogue.

In a lengthy interview with Esquire, the "San Andreas" star revealed that he received an unsolicited letter from none other than Spielberg himself. According to Johnson, the letter said:

"Been enjoying your movies over the years. Very entertaining. I feel like I've really gotten to know you over the years, most recently after watching you host Saturday Night Live. Great job, You continue to go for it. Proud of your work and look forward to meeting you. Steven Spielberg."

Johnson has been Hollywood's top earner over the last two years but even he was star struck by the note. Johnson said he was "blown away" by the gesture and took it as a sign that he had made it as an actor.

Here's Johnson enjoying the amazing moment.

 Grinnin' now like a big ass kid... When I was 8yrs old I sat front row to see a sold out INDIANA JONES in its opening weekend in Charlotte, North Carolina. I walked out of that theater excited and wanted to be "Indy".. cool, funny, charming with the ladies and kickin' ass w/ a smile. But at 8yrs old I was also perfectly content playing w/ my Star Wars figures and sneaking off listening to Richard Pryor concerts. Throughout the years I've credited this man and his movies as being my greatest inspiration in becoming an actor and wanting to always make "his kind" of movies - entertaining, quality and above all else.. heart. Just receiving this personal letter from him and its not only made me incredibly humbled and grateful, but it's also brought me back to being that 8yr old boy again who not only loves movies, but I now get to make the movies I love and enjoy the impact they have on others. THANK YOU STEVEN SPIELBERG for these inspiring and motivating words in your letter and cheers to making sure I'm always listening to that little voice in my gut. #CoolestGiftEver #BigAss8yrOldKid #SpielbergInspired
