Ever wanted to go back in time 20 years and change something?

“I wouldn’t change anything,” said Craig Robinson, a star of the new film “The Hot Tub Time Machine.”

“That’s not the message of the film,” Clark Duke replied, another star in the film.

The two gathered at Regal UA Horton Plaza Theatres Feb. 15 for the advance screening of the upcoming movie.

The preview was shown to a packed theater while the guests of honor sat in the back watching and listening to the audience’s reaction.

“The Hot Tub Time Machine” is about four friends who need a break from their adult lives, and during a vacation together they magically transport back to 1985. Because any changes affect the future, the friends struggle to relive a single night.

The movie will consistently make you laugh. The theater was never quiet for more than two minutes because this quick-witted cast coughed up one-liner after one-liner.

Robinson and Duke both commented that some lines were improved.

“The script changed a lot; the pages changed every day. I pitched a lot of new ideas,” Duke stated.

The cast also stars John Cusack and Rob Corddry. This comedic foursome had as much fun shooting the film as their characters did in the movie.

“We did a lot of bits,” Duke commented. He went on to tell a story about, after a late night of drinking, Cusack, Corddry and himself kicking in the door to Robinson’s room and giving him a huge scare. The whole time Robinson recalled the night he was laughing to tears.

Most of the shooting was done in Canada, which made filming in the frigid weather the most challenging thing for Duke.

Robinson replied with a different answer, “Being hungover.”

The film will be released to theaters nationwide on March 26. But why should you go see it?

“It is funny; even if you don’t find it funny, it is worth it to see (the one you came with’s) joy,” stated Robinson. Then he screamed, “I love it; do you all love it?”

The two were also in town as the Grand Marshals to the Mardi Gras Parade in the Gaslamp District, which was held on Fat Tuesday, Feb. 16.

Look ahead for these actors as they have plenty of roles lined up. Upcoming movies for Duke include “Kick Ass” and “A Thousand Words.” Robinson is still shooting episodes of “The Office” and will be in theaters again soon with his films “Shrek Forever After,” “The Other Guys” and “Father of Invention.”
