The Shakespeare in Love actor currently stars in fantasy drama Camelot, which airs on Starz in the US and begins this Saturday on Channel 4 in the UK.
He told the Radio Times: "I look at the quality of drama and writing on television and I look at the generic, formulaic, clichéd five acts of film, and I kind of go, 'Which would I rather watch?'."
He continued: "Television is actually the big screen [because] everyone's got a plasma and surround sound. So now you can see the quality of a film on your television."
The former FlashForward star also confirmed that he previously turned down a five-film deal with a major studio.
"I was offered that, but I just wanted to be free," he explained. "I want to [be able to] say 'I've never done television, let's have a go at FlashForward'."
Camelot begins this Saturday at 9pm on Channel 4, and continues on Fridays at 10pm on Starz.
