Lautner stars alongside Hollywood heavyweights Julia Roberts, Jennifer Garner, Jessica Biel, Bradley Cooper and Jessica Alba in the romantic comedy, as well as his ex-girlfriend Taylor Swift.
But Meraz is not impressed by the line-up and has attacked movie studio bosses for assembling such a headline-grabbing cast just to cash in at the box office.
In a series of tweets on his Twitter.com page on Thursday (04Feb10) Meraz wrote: "Sorry Taylor but the movie Valentine's Day looks lame and desperate. It cries out, 'look we have all the biggest starz in 1 movie pleez (sic) watch!'
"P.S. it has nothing to do with the talented actors in the movie. I just don't like the producer & Director's 'get rich quick skeem' (sic) nuff (enough) said."
Meraz later realises his comments might cause some controversy and takes to the social networking site to vow not to post similar outbursts in the future.
He adds, "Talk about biting the hand that feeds me... I'll be careful next time I spill twitter all over everyone."
