With Halloween exactly two weeks away, many people are still scrambling to find costumes or decide what to dress up as. Television shows and films have proven to be the most popular sources for costume ideas.

One of the most popular costumes both for adults and children, though mostly for kids, are based on the characters from Disney's "Frozen." According to the Canadian Press, across the border Elsa costumes have been flying off the shelves, but costumes based on Anna and Olaf are also popular.

DNAinfo reports that costume storeowners in New York are also struggling to meet demand for "Frozen" related costumes.

Party City has a children's Elsa costume for $29.99 and Target has various Elsa costumes at different price points, as well as a blonde Elsa wig for $10.

Another popular costume is Maleficent from Angelina Jolie's movie based on the "Sleeping Beauty" villain. This costume is more popular with adult women.

"Maleficent is just smoking hot this year," said the president of costume store chain Ricky's NYC, Richard Parrott. "Costumes are flying off the shelves."

Party City has both sexy Maleficent and traditional Maleficent, both for $49.99.

However, Disney is not the only popular source for costume ideas. The success of "The Walking Dead" has meant a rise in zombie costumes.

"We've had zombie requests just (like) crazy," Christine Riddell, manager of a costume store, told the Canadian Press. "We did last year as well, but we find that we're selling more blood, and people are looking for just an absolute variety of costumes you can throw blood on and zombie-fy anything."

According to DNAinfo, "Guardians of the Galaxy," especially Star-Lord and Rocket Raccoon, are popular costumes for men, both adults and children. Target has many "Guardian of the Galaxy" costumes and accessories. Many accessories are below $20 while a men's Rocket Raccoon costume costs $59.99.

However, thanks to the reboot of "Teenage Mutant Ninja Turtles" many of the costumes from the film have become popular this year. In Party City TMNT costumes are available for children and adults starting at $19.99 to $39.99.
