Captain America actor Chris Evans fights alongside Sonic the Hedgehog in concept art for the movie. Paramount's marketing for the video game adaptation did not begin with a good nod from viewers when the first trailer dropped last year. It featured an unrealistic version of the blue hedgehog. As a result, the studio delayed the film by three months. This gave the director Jeff Fowler and the team of VFX artists time to redesign the CGI Sonic. Luckily for Paramount, the redesign only cost a reported $5 million since the majority of the film's effects had not finished by that point.
In the end, the move proved a success. Sonic the Hedgehog earned positive reviews and set a new opening record for movies based on video games. Following the film's success, people started to take a closer look at how the project evolved over the course of its development. They went back to the time of Sonic's original rejected design. It turns out, he wasn't the only character in the film who got a makeover from the initial conception.
Twitter user Marx Pan posted a concept art for the movie from 2018 to their account. The caption read. “SonicMovie I found this concept art from an artist who worked with Jeff Folwer in early 2018, showing the original movie Sonic fighting alongside Chris Evans as Tom, he also posted several pieces of art in Weibo.” The art depicts a scene where Sonic and his human friend, Tom Wachowski, get into a bar fight. But in this scene, Tom gets portrayed by Evans and not James Marsden (who plays the character in the final movie).
Reports stated Paul Rudd was being considered to play Tom in May 2018. Later, Paramount officially cast Marsden in the role. In December, someone leaked an alleged internal casting shortlist. Among the actors on the list were Evans and Rudd, along with Chris Pratt and Michael B. Jordan among other big celebs. The leak included a poster featuring Pratt as Tom, so Evans was not alone. Evans was busy working on Avengers: Endgame when he got considered to play Tom in Sonic the Hedgehog. He later began shoot for Knives Out, a month after the film began production.
