Morgan Freeman, a revered actor himself, shared that he, too, was inspired by Sidney Poitier's grace and professionalism.
The 84-year-old Oscar winner paid tribute to the legendary actor who died on Thursday.
Morgan took to social media and wrote, "Sidney was my inspiration, my guiding light, my friend. Sending love to Joanna and his family."
Morgan rose to prominence in the 1970s after appearing in the children's television show Electric Company.
His breakout role, however, came in Street Smart, which earned him an Academy Award nomination in 1987 for Best Supporting Actor.
By then, Poitier had long cemented his place in Hollywood as a driving force, with an Oscar nomination for Best Actor in 1958 for The Defiant Ones
and, in 1964, becoming the first Black man to win in that category for his role in Lilies of the Field.
With Poitier serving as his inspiration, Freeman would go on to earn Oscar nominations for Best Actor in 1989 for his role in Driving Miss Daisy, and again in 1994, for The Shawshank Redemption.
Then, in 2004, Freeman scored his first Oscar win for Best Supporting Actor for his role in Million Dollar Baby.
The Oscar for Best Actor, however, proved elusive once more in 2009 (Invictus).
