In the television show "The Big Bang Theory," engineer Howard Wolowitz lived most of his life without ever really knowing his dad, since his father left him and his mother Debbie (voiced by the late Carol Ann Susi) when he was only 11 years old.

During the eighth season, he found out that he actually had a half brother, and a few seasons back, Sheldon discovered a letter written by Howard's father to him, explaining his absence in his life. In turn, Sheldon told their group of friends about the letter, and Howard was the last to know about the letter's existence.

This really infuriated Howard, who half wanted to know and half didn't why his father left him and his mother. So to make up for it, all of his friends told him their own version of the letter's contents, but only one of it is really real. That way, Howard both knew and didn't know the real reason for his father's departure.

During an interview with The Irish Examiner, Simon Helberg, the actor who portrays Howard really wants his character to be reunited with his father.

"I think it would be nice to potentially meet his dad," he said. "I like it when the writers get deep because it's hard to do that on a sitcom without hearing the cheesy violin or having that special episode feeling, and they do it so well and I love getting to learn about this character I've played and known for over seven years, and getting to discover things I never knew.

"I don't write the show, I don't create any of those aspects so I get a script, open it and find out his dad abandoned him. It's interesting. I can't wait to see what they've got for us," he added.

One thing he's really happy about his character's situation now is that his work doesn't require him to be away anymore. "I don't need to go back to space," he jokingly said.

Aside from "The Big Bang Theory," Helberg is now promoting his new film called "We'll Never Have Paris," which is based on his disastrous real-life engagement to wife Jocelyn Towne.

Helberg said that being cast in "The Big Bang Theory" has its own pros and cons when it comes to making his own film.

"It definitely helped in many ways, and I also think there are setbacks that come with it too because it's in a completely different universe that my film exists in. It's something I'm learning about now, about how those worlds affect each other," he said.
