Oddly atypical of Sellers' work, Trial and Error presents Sellers as a hapless attorney assigned to defend Attenborough, who in a fit of rage, has killed his buffoon of a wife. Sounds good so far, but Sellers strays far and wide from his patented farce-master schtick, and while he should be commended for extending his range, the experiment on the whole is not successful. Attenborough is altogether forgettable, but the film's avant-garde use of flashbacks is worth a peek.
Aka The Dock Brief.
