Keeping certain parts of the body nice and neat isn’t just the responsibility of females, Colin Farrell discovered while filming his first ever big-budget film, Tigerland, back in 2000. 

Fondly known as the Lusty Leprechaun back in those tabloid days, Colin, 41 later this month and now 10 years sober, told his friend Ellen DeGeneres on Monday that he was self-conscious about how he looked down there because the role called for a sex scene which he had never done before. "I went up to the director, Joel Schumacher, and had a dressing gown on and nothing underneath,” Colin said.

"I was obviously so nervous I lost my mind for a second, and opened my dressing gown and said, 'Is this a bit... is it a bit...' – because I had, like most men, what you could refer to as a retro bush – and Joel the director kind of went, 'Oh…' So I said, 'I'll trim it!'"

He headed straight for hair and makeup and borrowed a beard trimmer, but the DIY job didn’t go so well, he recalled.

“I trimmed the right side a little bit, then obviously had to match it and trimmed the left, but overshot the mark a little bit. Had to get back in, approach the right again, overshot that," he said to the delight of Ellen and her audience.

“At this stage I was sweating. And I went back in and re-approached the landing on the left, and then I looked down and I had a little landing strip.”
