Because Sweeney Todd was filmed on a soundstage, all the London backdrops needed to be created in the computer. 

TDB: How much time from bid to picture lock did you have to create your pieces?

GB: The whole show lasted about 10 months internally, 11 if you count a few test shots. Post was about four to five months. Some shots/environments required up to six months of work, others were done in weeks.

TDB: What systems and software did you use?

GB: Maya, PRMan, Shake, Photoshop and a host of in-house developments: most specifically, software and plug-ins written for the purpose of space and object recreation based on photography.

TDB: How many artists were on the project?

GB: The team was between 50 to 70 artists throughout the shoot and post period.

TDB: When all is said and done, what sequence or element is your favorite in the film?

GB: Eek, my favorite? It's the truly invisible effects shots and sequences that I like best. They are also usually the hardest. There's a few shots mixed into sequences we did that I know no one will question their realistic integrity. They're my personal favorites.
