Arrow is getting ready for its fifth season on CW, and there is a big crossover planned for December. The crossover will feature the CW’s latest superhero series, Supergirl, and Arrow, The Flash, and DC’s Legends of Tomorrow.

Producing a crossover between four shows will not be easy, and Willa Holland spoke about that challenge at London Comic Con over the weekend.

TV Line shared audio of Holland’s comments, and she confirmed that the crossover with Supergirl is happening this upcoming season, and she is excited for it to happen.

However, it will be difficult to film the crossover, and she made that clear. She did joke about the crossover though. She said the following:

“All I’ve got to say is I want to be on Earth-Two. It seems so much better than regular Earth!”

Holland also spoke about the DC Universe on television, and she expressed her feelings on the separation between the DC world on television and in the movies. DC keeps the two very separate, and that will not change.

Holland said the following, according to Digital Spy:

“It does work [combining the two], because Marvel does it – the mash between their Agents of SHIELD into the movies. So it is a little upsetting because you know it is possible and it can be done and how good it would be if it was done.”

The separation between the two forced Arrow to axe their Suicide Squad plot once DC decided to make their own feature film. That film will be released later this summer.

Arrow will return to CW this fall. Are you excited for the return of this series? Tell us what you think.
