"I'll Find You" has an excellent international cast. Robert and Rachel, main characters, were played respectively by Leo Suter, a rising star from Great Britain and by Adelaide Clemens, talented Australian who already appeared in such exceptional movies as "The Great Gatsby" or "Generation Um". Ursula Parker from New York and Sebastian Croft from London (nominated in 2019 for junior BAFTA) played Robert and Rachel as children.

David S. Ward, American director and author, Oscar-winner for the screenplay to "The Sting", Oscar-nominated for "Sleepless in Seattle", shares the screenwriter credit of "I’ll Find You" with Bozenna Intrator, Polish-American poet, screenwriter, and movie producer. Jan A.P. Kaczmarek, the Polish composer who wrote music to more than 60 movies, including “Finding Neverland” for which he received an Oscar, wrote the music to “I’ll Find You”.
