Chris O'Donnell brings a quiet intensity to his work on NCIS: Los Angeles, but when not playing "G" Callen on CBS' hit drama, the actor is all smiles and laughs on the Emerald Isle.

Watch photographed the beloved actor at the legendary Ashford Castle in County Mayo, Ireland for our March-April 2013 issue. Here's a look back at his lucky adventures.

LL COOL J living his best life

"I just love the composition and candid realness of this photo. LL COOL J was in Paris for a Watch cover shoot and his presence is just larger than life!" — Christopher Ross, Director of Photography

Chris O'Donnell getting his fashion game on

You see this position a lot during a golf game. Chris O'Donnell really got into this shoot and gave us all the posed subtleties of a championship game. He just wears white pants so well! — Christopher Ross, Director of Photography

Daniela Ruah looking like rain drops on roses

Photography by Cliff Lipson. Originally published in Watch Magazine, March-April 2018.

"We all pray for beautiful weather when we photograph our stars, but on the day of this shoot in Los Angeles, it was rain city. Nevertheless, Daniela Ruah playfully worked around the precipitation and was absolute perfection for this cover shot montage." — Ed Mann, Creative Director

Eric Christian Olsen showing off his playful side

Chris O'Donnell channeling his roots

Photography by Cliff Lipson. Originally published in Watch Magazine, April 2013.

"For his first cover shoot with Watch, we took Chris O'Donnell to Ireland. Ashford Castle was the location and the whole crew was blown away by its beauty. The NCIS: Los Angeles star got those waders on and paddled our photographer Cliff Lipson into the middle of the lake to get this shot!" — Christopher Ross, Director of Photography

Daniela Ruah delivering that California dreamy

"Daniela Ruah was so wonderful during this photo shoot. She was very patient and happily waited for us to capture that perfect golden hour shot."— Alice Ross, Deputy Photo Editor

Photography by Cliff Lipson. Exclusive to CBS.com.

"Each year we get one shot of photographing our stars before the new TV season starts. It's pretty much a fire drill! Fast-paced photography on the red carpet that's over before you know it. And then walked in Renée Felice-Smith to our TCA photo booth in this amazing Bohemian look that made time stop. So poised, sweet and confident. Beautiful!" — Ed Mann, Creative Director

LL COOL J shining in the City of Light

Two images side by side of LL COOL J smirking in a denim outfit

Photography by Gilles-Marie Zimmermann. Originally published in Watch Magazine, December 2014.

"Few actors have that sense of presence off stage, that commands attention. LL COOL J is without a doubt, one of those stars. He simply captivated the streets of Paris, and our team." — Ed Mann, Creative Director

Dynamic duo LL COOL and Chris O'Donnell doing what it takes to get the shot

LL COOL J standing by the passenger seat and Chris O Donnell standing by the hood of a silver car

Photography by Cliff Lipson. Originally published in Watch Magazine, October 2009.

"This shot cracks me up. At the last minute there was a scheduling conflict and we could no longer shoot LL COOL J and Chris O'Donnell on the same day. What you see here is a cool composite after two days of shooting each actor separately—luckily both at the Peninsula Beverly Hills. Talk about teamwork!" — Christopher Ross, Director of Photography
