Colin Farrell, the former "Lusty Leprechaun" whose party-fueled lifestyle landed him in rehab in late 2005, practiced a not-so-random act of kindness while stumping for the Woody Allen-directed flick "Cassandra's Dream" this week at the Toronto International Film Festival.
The Toronto Sun reports the scruffy star was signing autographs outside his hotel when he spotted a homeless gent he'd met three years ago, when he was in town filming "A Home at the End of the World."
Turns out Farrell had taken advantage of a radio promotion offering $2,000 to anyone who could deliver him to the station, collaring the guy -- nicknamed Stress by locals -- and helping him claim the bounty.
The paper says his Irish eyes were a-twinkle at the reunion, and he urged his down-and-out acquaintance to climb into his chauffeur-driven car.
Then, in a Bizarro version of the makeover montage from "Pretty Woman," Colin accompanied Stress to a Europe Bound Travel Outfitters outpost, which sells everything from clothes to tents.
"Get him anything he wants," Farrell reportedly told the employees, who fetched his new pal a $500 coat, a high-end sleeping bag and a rolling backpack filled with underwear, socks and boots, all useful for the coming Toronto winter.
"Cool guy," the store's manager tells the Sun of the actor. "He doesn't act like a movie star."
According to the staffer, Colin had an easy rapport with Stress, who was "going around, grabbing stuff."
The bill for the philanthropic shopping trip came to more than $2,000, but Farrell's beneficence didn't end there.
He also hit a nearby cash machine, withdrawing a stack of bills and reportedly arranged to pay for a year's rent on a room for what we're now guessing is his biggest fan.
"I'm all set up," Stress is quoted as telling a local. "This is my chance to get off the street."
The paper estimates that Farrell's generosity set him back around $10,000.
