Rocky Johnson's death

Dwayne Johnson opens up about his dad's 'quick' death and thanks supporters

The actor's legendary pro-wrestling father, Rocky Johnson, passed away last week at age 75.

The younger Johnson posted an almost eight-minute video Sunday on his official Instagram account in which he expressed his appreciation.

"Hard to express how deeply grateful I am for all your love, mana & support," the caption read. "My family and I thank you. Go hug your loved ones hard, while you still can. I love you. DJ #ripsoulman."

The wrestler-turned-actor said during the video, "My heart is so full of gratitude."
