One of his most significant roles was in 1981 when he starred in the romantic-comedy The Four Seasons, which centres on a group of married friends.

The film has been transformed into a Netflix series by Mean Girls' Tina Fey, along with Lang Fisher and Tracey Wigfield, with all eight episodes released earlier this month.

In the original The Four Seasons, Cariou plays Nick Callen, whose midlife crisis acts as a catalyst for the rest of the friendship group to reassess their own relationships.

Now aged 85, the Blue Bloods star was in his mid-40s when he featured in the rom-com, sporting dark to greying hair and a leaner physique.

In the 2025 Netflix adaptation, Cariou's character Nick is portrayed by actor and comedian Steve Carell.

He is best recognised for his role as Michael Scott in The Office US, but has also appeared in Crazy Stupid Love, The 40-Year-Old Virgin and provided the voice for Gru in the Despicable Me franchise.

Steve Carell teams up with actress and creator of The Four Seasons, Tina Fey, who steps into the role of Kate Burroughs, a part originally played by the iconic Carol Burnett from Annie and Better Call Saul fame.

Joining them is Saturday Night Live alumni Will Forte as Jack Burroughs, taking over the baton from MASH superstar Alan Alda, along with Coleman Domingo from Fear The Walking Dead, filling the shoes of Danny Zimmer, a role once held by The Ritz's Jack Weston.

Despite no new projects listed on Len Cariou’s IMDb page as Blue Bloods winds down, co-star Abigail Hawk hinted at his continued zest for work in an interview with Us Weekly: "He's 85 years young.

"One of the coolest things about our show, aside from like the family dinners and aside from [the fact that] obviously these people are beloved, is that we show that age is really just a number."

Blue Bloods is available to watch on CBS.
