The third episode of Dancing With the Stars season 17 airs Monday night on ABC and will feature the celebrities dancing to songs from movies.

It's Hollywood Night on the celebrity dancing show and the 11 remaining celebrities are finalizing their routines in anticipation of Monday night's show. The twist is that they must dance to a movie song from a different decade as their competitors.

The celebrities have offered a few hints about what to expect from their dances Monday. The Dancing With the Stars Twitter account posted a photo of comedian Bill Engvall with partner Emma Slater in cowboy hats, indicating that they will be saluting '40s or '50s Westerns.

Meanwhile, High School Musical star Corbin Bleu posted a photo on Facebook of himself on the set of 1999's Galaxy Quest, indicating that he may be tackling the '90s with partner Karina Smirnoff.

Going into the third week of competition, viewers are getting a clearer sense of which acts are in it for the long haul and which will likely face elimination soon.

Bleu, Glee star Amber Riley and actress Elizabeth Berkley Lauren have not received a score below 24 out of 30 since the beginning of the competition. Assuming their dancing continues to be better their competitors and they get support from viewers, the three celebs will likely be dancing until the end of the season.

At the bottom of the chart, Engvall, TV scientist Bill Nye and sitcom legend Valerie Harper may not be dancing for much longer. All three stars are the oldest in the competition and may have enough of a fanbase to carry them through, but the judges have not been as impressed by their dancing skills.

At the end of Monday night's show, the judges' scores will be combined with the public vote from last Monday's show. This will determine which celebrity will be eliminated from the competition.

Tune in to Dancing With the Stars Monday at 8 p.m. on ABC to see the 11 remaining celebrities perform another dance as well as the second elimination of the season.
