3. Aman Mathur in Kal Ho Naa Ho (2003)
Khan’s portrayal of Aman Mathur, a terminally ill man with a zest for life, is both heartwarming and heartbreaking. Despite his own feelings, Aman plays matchmaker for his love, Naina (Preity Zinta), encouraging her to be with another man who can give her a future. His selfless love, humour, and the way he teaches Naina to embrace life make Aman a memorable and poignant character, bringing audiences to tears and underscoring the depth of his love.
