Old Man Marley from Home Alone is most commonly identified as the elderly neighbor played by actor Roberts Blossom. Blossom was born on March 25, 1924, and died on July 8, 2011, which would make Marley a character depicted as well into his 60s or older in the film’s timeline, depending on production notes and the actor’s age during filming. In real-world terms, the actor was 66 at the time of filming and was 66–66 years old around the release year 1990, with contemporary references sometimes adjusting for exact production dates. For quick context, the character’s “mysterious neighbor” persona is deliberately aged to appear as a cautious but kindly elder figure.

• Real-world age of the actor: Roberts Blossom was born in 1924 and died in 2011, aged 87. This places him in his mid-60s during the 1990 production window for Home Alone.

• On-screen portrayal: Old Man Marley is depicted as an older, reclusive neighbor who is later revealed to be benevolent, forming a friendship with Kevin. The character’s age in-universe isn’t explicitly stated in the film, but the performance aligns with an elderly, second-half-of-life silhouette.

• Production context: Home Alone released in 1990; Blossom’s age during production would have been about 66. This aligns with widely cited biographical notes about the actor.
