Director Michael Bay briefly threatened to pull out of a sequel to Transformers after Paramount Pictures dropped the next generation Blu-ray DVD format.
Bay's films include Transformers, Bad Boys and Armageddon
"No Transformers 2 for me!" wrote the director on his personal website. "To deny people who have Blu-ray sucks!"
But his comments were replaced several hours later with an apology as Bay confessed: "I over-reacted."
On Monday, Paramount and DreamWorks said they were dropping Blu-ray in favour of the rival HD-DVD format.
The announcement means that blockbusters like Shrek the Third, and Bay's Transformers film, will not be released on Blu-ray.
Movies directed by Steven Spielberg, however, will continue to be released in both formats.
Electronics giant Sony, which owns Blu-ray, is locked in a battle for supremacy with Toshiba, which created HD-DVD.
Each format offers a higher quality of picture and sound than current DVDs.
Blu-ray discs have more storage space, which can mean a better image, while HD-DVD offers more interactive features.
The latest Spider-Man film will only be released on Blu-ray
The race for dominance is reminiscent of the format war between VHS and Betamax video tapes in the 1980s.
The Blu-ray camp has notched up some victories against its rival recently, including a vote of support from video rental company Blockbuster.
Prices of players on both sides have dropped recently - with dedicated HD-DVD players outselling Blu-ray in the US.
However, the fact that Sony's PlayStation 3 games console can play Blu-ray discs means more homes have Blu-ray players.
It is believed that Hollywood studios could ultimately decide the fate of the two formats, but the fact that Sony is itself a movie studio has complicated the matter.
Warner Brothers is now the only company to release films in both formats, meaning that Spider-Man 3 will be a Blu-ray exclusive, while The Bourne Ultimatum will only be available on HD-DVD.
Aside from Bay, several film-makers have voiced their support for different formats.
Transformers 2 is "back on," Bay commented on his website
Producer Jerry Bruckheimer, who is responsible for Pirates of the Caribbean series, said Blu-Ray "far surpasses any other format".
A spokesperson for Dreamworks Pictures told film trade paper Variety that Steven Spielberg was also "a supporter of Blu-ray", although he added: "He is not exclusive to either format".
Bay, whose previous film credits include Bad Boys, Pearl Harbor and Armageddon, wrote on his website that he had been converted to HD-DVD after watching war epic 300.
He explained his original comments were written late at night after friends had complained they would not be able to watch Transformers on Blu-ray.
"As a director, I'm all about people seeing films in the best quality possible, and I saw and heard first-hand people upset about a corporate decision," he wrote.
"I heard where Paramount is coming from, and the future of HD, and players that will be close to the $200 (£100) mark which is the magic number. I like what I heard," he said.
"So I think I might be back on to do Transformers 2!"
