I have a tough time reviewing movies starring Ewan McGregor as the guy happens to be my favorite actor. But, fortunately, putting together a Top Picks list is a matter of personal choice, so it's totally fine to play the fan and not have to be professionally disconnected from the subject. That said, here are my choices for some of the best Ewan McGregor movies (and no, any movie with "Star Wars" in the title will NEVER make this list).
1. "Trainspotting"
Danny Boyle directs Ewan McGregor, Jonny Lee Miller and Robert Carlyle in this probing look at the lives of heroin junkies in Edinburgh. 
2. "Moulin Rouge"
Some thought it wouldn't work but Ewan McGregor and Nicole Kidman just went for it in this flashy, energetic movie musical from filmmaker Baz Luhrmann.
3. "Velvet Goldmine"
Ewan McGregor doesn't mind dropping his pants on film, and "Velvet Goldmine" allows him to let everything hang out - but not gratuitously. Jonathan Rhys-Myers and Christian Bale co-star in Todd Hayne's critically acclaimed look at glam rock.4. "Big Fish"
This wild fantasy from Tim Burton has a touching message about family and love. If you like tall tales, and if you're looking for a gentle Ewan McGregor movie, then this one's for you.5. "Down With Love"
Ewan McGregor plays Rock Hudson to Renee Zellweger's Doris Day in this under-appreciated romantic comedy. Be sure to watch all the DVD extras - and stay tuned to the credits for a cute song and dance number by McGregor and Zellweger.6. "Rogue Trader"
Ewan McGregor's performance single-handedly makes this movie worth watching. McGregor stars as stockbrocker Nick Leeson, a guy who plays it loose and gets in way over his head in this dramatic thriller, based on true events.7. "A Life Less Ordinary"
Sometimes I'll tell people I love this movie and I'll get the strangest blank looks in response. Apparently "A Life Less Ordinary" is a well-kept secret. But check it out - Ewan sings, dances, gets really emotional, and woos Cameron Diaz.8. "The Pillow Book"
Unusual and sensual are two words commonly used to describe "The Pillow Book," a 1996 film starring McGregor and Vivian Wu.9. "Shallow Grave"
You've got to love this movie's tagline: "What's a Little Murder Among Friends?"
