Nyong'o doesn't have a huge role in the film, but her character Gwen distinguishes herself by being very kind, particularly when she provides comfort to a small girl who's travelling alone.
She also looks beautiful in her Star Trek-ish uniform.
Dockery plays the main stewardess Nancy, who helps Liam Neeson as he tries to catch the bad guy. She also believes in him when everyone else thinks he's a bum.
Also, I think she's sleeping with the co-pilot.
FIRST ROUND: DOCKERY
With a Best Supporting Actress Oscar nomination for her role in 12 Years A Slave, Nyong'o is one of the hottest actresses going right now.
This 30-year-old Kenyan Yale graduate has also written and directed films and videos in her native Africa.
Dockery is no slouch herself, having starred in the mega-hit TV show Downton Abbey over the past four years.
This 32-year-old English rose has done tons of television and her next movie is Selfless with Ryan Reynolds.
SECOND ROUND: NYONG'O
Over the past couple of weeks, it's been rumoured that Nyong'o is dating US actor Jared Leto!
He's been nominated for an Oscar just like her (Best Supporting Actor for Dallas Buyers Club), and the two have been very chummy at all the recent award shows. The rocker-frontman is who I'd choose if I liked dudes.
Dockery doesn't date very famous people.
What's wrong with her? She went out with an architect for a few years before hooking up with actor Joseph Millson.
Who's he? Then she broke up with him and started a romance with some Irish finance-type guy. Lame!
THIRD ROUND: NYONG'O
Nyong'o has a great career and a great (rumoured) boyfriend, but Dockery seems nice as well. I hope we can all be friends
