Actor Ryan Reynolds teased his upcoming movie "Deadpool" with a full costume of the Marvel superhero he portrays during the Halloween celebration.

According to TheWrap, the main actor of the movie posed with a group of kids on a trick-or-treat adventure.

In a tweet, Reynolds posted the photo of his costume with the caption "Dear Fox, stop changing the timelines. It's confusing the audience. #xmenassemble."

He had a different caption on his Instagram post: "Remember, tonight we set our clocks back 34 years. #happyhalloween."

TheWrap noted that the costume worn by Reynolds looks so legitimate in the post that it may be the real costume on the set of the X-Men spinoff.

Last January, Reynolds reportedly said that he has waited a long time to play the role of "Merc with the Mouth" so he is determined to take home a souvenir.

"I loved wearing it and I have run away with one -- I'll probably get into trouble for saying that, but I've waited 10 years to do this movie so I'm leaving with a f-king suit," he was quoted by the TheWrap as saying.

Cinema Blend added that Reynolds was a die-hard "Deadpool" fan and playing the character of mercenary Wade Wilson was a dream come true for him.

The movie, as per IMDB, is about "the most unconventional anti-hero," Deadpool. The main character is reportedly a former Special Forces operative who became a mercenary.

"Wade Wilson, who after being subjected to a rogue experiment that leaves him with accelerated healing powers, adopts the alter ego Deadpool. Armed with his new abilities and a dark, twisted sense of humor, Deadpool hunts down the man who nearly destroyed his life," added IMDB.

Aside from Reynolds, "Deadpool" also stars Hollywood's biggest names like Morena Baccarin, Gina Carano, Stan Lee, T.J. Miller and Ed Skrein, among others.

Expected to be shown on theaters on Feb. 12, 2016, "Deadpool" is expected to have a PG-13 rating or an R rating to encourage more individuals especially the young ones to enjoy the movie.

Screen Rant added that the movie "does everything right."

"It addresses, pokes fun at an distances itself to X-Men Origins: Wolverine where Ryan Reynolds first played a version of Wade Wilson. It features Reynolds in the actual movie Deadpool costume - as revealed for the first time last week," added the same report.

When the movie's trailer became available in August, Forbes said that it was able to present an "impressive" offering by 20th Century Fox.

"You get the snarky fourth-wall banter, complete with an all-too-obvious shot at Green Lantern, you get the R-rated violence played for laughs and the uncommon (for the genre) four-letter words tossed in for good measure," added Forbes' writer Scott Mendelson.
