He has also been involved in ad campaigns for brands such as Cheerios and Smarties.
'Alexander and the Terrible, Horrible, No Good, Very Bad Day' will be produced by The Jim Henson Company and 21 Laps.
Carrell can currently be heard reprising his role as loveable reformed villain Gru in animated caper 'Despicable Me 2', while Garner recently began filming sports drama 'Draft Day'.
