Today Tron Legacy finally debuts in theaters after 3 years of heavy campaigning from Disney Studios. The follow up to their 1982 feature Tron is expected to introduce a new generation to the mythology surrounding Kevin Flynn and his son Sam. According to Deadline, the movie is off to a good start by earning $3.5 million at midnight screenings on Thursday night.

The amount may not seem that huge in comparison to other openers like Harry Potter and the Deathly Hallows, and The Twilight Saga: Eclipse, but take this into consideration: 25% of its gross came from IMAX. That’s a record for the company! Tron Legacy grossed about $1 million from the 228 IMAX locations where it was featured.

By far, the 25% is the largest IMAX take from any movie’s midnight box office including Iron Man 2, Inception, and even Avatar. But with that, Legacy still isn’t the largest IMAX opening ever. We’re not sure if it will be able to beat current champ Harry Potter and the Deathly Hallows Part I and their $11.8 million opening.

We’re not surprised that Tron Legacy had more IMAX viewers than anyone else. It’s Tron! It’s one of those movies that you should see in the best possible conditions. IMAX is definitely the way to go.

What do you think of Tron Legacy’s midnight gross? Will you see the film in conventional or IMAX theaters?
